Technology has advanced ultrasound free essay sample

Abstract The 1960s introduced the use Ultrasound to the medical field. Since the introduction of Ultrasound there has been many technological advancements that have greatly improved ultrasound imaging and quality of diagnosis results. These advancements include 3D/4d imaging, Pure Wave transducer, Color Doppler, and Point-of-view. Advancements do to technology has lead Ultrasound to be the second most used diagnostic tool in many medical fields including cardiovascular, obstetrics, pediatrics, gynecology, neurology, and emergency care. Introduction Ultrasound is currently the second most used diagnostic imaging modality in medicine, due to the technology advances and improvement. Since introduced to medical care in the 1960’s ultrasound has dramatically improved. Technology advancements have led to the development of 3D/4D imaging, pure wave transducers, color Doppler, and point-of-care ultrasound. With these advancements has improved the overall health care. 3D/4D Imaging Imaging technology has advanced from the original 2D imaging in the 1960’s, to incredibly advanced 3D/4D imaging. We will write a custom essay sample on Technology has advanced ultrasound or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page 2D imaging provided only outlines and flat looking images, leaving much unseen by doctors. As technology advanced in the late 1980’s, computer programs were able to produce 3D images. 3D ultrasound allowed doctors to see width, height, and depth of images. However, the technology advancements of ultrasound imaging from the past few years, have made the most dramatic improvements in the ultrasound imaging. The most recent advancement in ultrasound imaging, is the development of 3D/4D and 3D/4D-real time ultrasound imaging. 3D/4D ultrasounds provide very detailed, life like images that provide more accurate measurements and diagnoses. While 3D/4D-real time provides the same results, it also becomes a moving image that is continuously updated in real time as the patient is being scanned. This new advancement in ultrasounds has greatly improved health care, specifically in obstetrics. In the first trimester of pregnancy, 3D/4D ultrasound can demonstrate normal and abnormal fetal anatomy with exquisite detail. Detailed imaging of the umbilical, spine, head and face, genitalia, and extremities is possible. This provides improved diagnosis in the first trimester, limiting the need for more invasive imaging techniques. 3D/4D greatly increases the evaluation of the fetal skeleton. Obtaining detailed structural information about the spine is important in evaluating fetuses at risk for skeletal dysplasia. With 3D/4D ultrasounds the umbilical cord and its insertion sites are readily visualized and abdominal wall defects can be accurately and thoroughly studied. With 3D/4D it has become possible to accurately measure the volume of fetal organs and assess growth and development. Although 3D/4D has improved health care throughout the entire medical field, critical improvements can be seen in just obstetrics. Technology has advanced ultrasound imaging, but also much more. Pure wave transducer In the 1960’s transducers could only provide 2D images. New technology has led to the development of x6-1 pure wave xMATRIX transducers. Pure wave transducers provide high-resolution images, for either 2D or 3d/4D. Transducers can now deliver both 3D/4D and 2D images with just the click of a button. The ultra-thin, target beam provides tissue uniformity, resulting in less artifacts. Current transducers can also take images from two planes simultaneously without rotating the transducer in which takes away the risk of losing tiny objects. Transducers now provide medical instrument navigation, which helps guide medical tools during internal procedures. Unlike old transducers, new technology allows transducers to provide high resolution images, even in the most difficult anatomy. Leading to early detection and treatment of tumors. These improvements have allowed physicals to see things that are a lot smaller and deeper, which were unable to be seen before. With these technological improvements physicians can see in much more clearer definition. â€Å"Everyone is so use to ultrasound pictures being fuzzy,† said Tomo Hasegawa, director, ultrasound business unit, Toshiba America Medical Systems. â€Å"With enhancement in computer technology, we’re starting to get images that are so clear, people don’t even realize its ultrasound. † Color Doppler Technology advancements have made ultrasounds capable of real-time color doppler flow imaging, and flow measurements. A color doppler is technology that displays blood flows information in color. Red indicates blood flow moving toward the transducer, while blue indicates blow flow moving away from the transducer. Variations in color shades indicate the magnitude of flow velocity. Color doppler make it possible to see blocked blood flow in the neck arteries that can cause strokes. It also makes it possible to see blood clots in leg veins that can black blood flow to the lungs. Color doppler has improved both stroke prevention and treatment. Color doppler has also improved fetus health care. Doctors can now see blood flow in the umbilical cord through the placenta, heart, and brain to see if the fetus is receiving enough oxygen. Without the technological advancement of color doppler blood flow and the cardiovascular system could not be examined and cared for. Cardiovascular system health care relies greatly on color doppler ultrasound. Point-of-care With technology advancing, ultrasound equipment has become more compact, higher quality, and less expensive. These advancements have led to point-of-care ultrasound, which is ultrasound that can be performed bedside and images can be obtained immediately, rather than recorded images that can be interpreted later. Point-of-care allows immediate diagnosis and procedure guidance. Emergency care has been greatly improved because of this, due to the almost immediate identification of life threatening injuries. Patient care has also been improved because they can now get diagnosed sooner and spend less time at the hospital. Point-of-care, resulting in more lives saved. As well as improved diagnosis accurately because the ultrasound is performed while the patient is experiencing symptoms. A New England journal of italic medicine review reported that point-of-care ultrasound â€Å"decreases medical errors and provides more efficient real-time diagnosis. † Conclusion These advancements of ultrasound have allowed it to become one of the most important and valuable diagnostic tools in medical areas such as cardiology, obstetrics, gynecology, surgery, pediatrics, neurology, and emergency care. Technical advancements are constantly being made, making it conceivable that every physician’s office may have ultrasound in the not so distant future.

Mondavi Corporation

Mondavi Corporation The Robert Mondavi Corporation Today the forces of globalization and consolidation are face to face with the wine industry. The old world producers: France, Spain, and Italy, continue to dominate the market while the new world producers such as the US, Argentina, Australia, Chile, and South Africa have been making inroads into the global and increasingly competitive wine market. The Robert Mondavi Corporation has produced some of the most respected wine labels around the world, gaining a reputation of superior quality. Mondavi is known throughout the world for its quality wines, but the percentage of international sales for the company is actually relatively small. In 1994, only 6 % of the company's $200 million sales were made outside of the United States. However, international operations represent a significant opportunity for the company to grow, especially in countries with markets that do not yet drink significant amounts of wine, for example Asian countries.20131117-OSEC-JC-00 03The company also has excellent opportunities in working with some of the new wine producing countries such as South Africa and Argentina. I believe that the key factor to success is to develop an internal commitment to an international relations program and support it with adequate resources.The Robert Mondavi Corporation has not dedicated a large staff to international development. I urge Mondavi to establish an international division structure creating a division designated to handle all of international operations. This structure takes a great deal of the burden off the chief executive officer, Michael Mondavi, and designates the head of the international division to coordinate and monitor all overseas activities. The vice-president of international operations reports directly to Mr. Mondavi regarding all international matters and this ensures that the international focus receives top management attention. This arrangement is good for the Mondavi Corporation because it is...

How to Style Profanity

How to Style Profanity How to Style Profanity How to Style Profanity By Mark Nichol Some time ago, I wrote about the suitability of profanity in prose. My conclusion was that, depending on the context, it’s up to the producer to decide whether to publish profanity and the reader whether to accept or reject it. But if you, the producer, decide to allow profanity, know that there are degrees of deployment. The simplest approach, of course, is to treat profane and obscene words and phrases just like any other. As I mentioned earlier, many people (myself included) find humor in judiciously employed cussing intended to evoke amusement, and nothing beats a string of expletives to convey passion of one kind or another. Understandably, however, this acceptance is not universal, and publishers must be sensitive to their readership. General-interest magazines and websites and the like, especially those with paid subscriptions and/or with a reputation to establish or uphold, are unlikely to allow such terms to parade across the page or the screen like rowdy revelers. Publications with niche audiences consisting of people who unabashedly use profanity in speech and writing, and hear it without flinching, are going to have a more relaxed attitude about provocative language. But what if yours doesn’t belong in that category? You, and your writers, can refrain from including profanity in your narrative, but what about reporting what another party wrote or said when the statement includes naughty words? In lighthearted contexts, writers and editors can bowdlerize comments with euphemistically droll descriptions along the lines of â€Å"Smith suggested that Jones engage in an anatomically impossible activity† or â€Å"She spoke, to say the least, in a manner inconsistent with what one would expect of a person standing among blue-haired ladies in the lobby of a church immediately after the service.† Coy references to utterances of â€Å"expletives† or â€Å"invective,† or to â€Å"colorful language,† also get the point across. But if one would rather tiptoe closer to verisimilitude, one might print a word with a nonalphabetical character in place of one or more letters, as many people do to circumvent profanity filters in the commenting function on websites. (Sh!t, for example, provides an orthographical fig leaf and additional emphasis in one stroke.) Some publications have a more restrictive policy: Print the first letter only, followed by a dash (or two hyphens) or a couple of asterisks: s, or s**. (The paired characters collectively represent, rather than correspond one to one to, the missing letters.) One might also employ what has been variously labeled a grawlix (the term was coined, among other similarly jocular vocabulary, by comics cartoonist Mort Walker) and an obscenicon (the creation of Language Log blogger Benjamin Zimmer). However, an ostentatious representation like @#*! this approach is said to have been invented by Rudolph Dirks, the creator of the pioneering comic strip The Katzenjammer Kids is best reserved solely for humorous use; alternatively, in a feature article or a column, a writer might simply refer to an f-bomb or the s-word rather than apply the news section’s substitution policy. Another necessary component of a publication’s rules about the use of profanity and obscenity is a word list that explicitly draws the line: Which words (like mild oaths) are acceptable in print, and which (sexual and scatological terms, for example) are not?

Epidemiological studies Essay Example | Topics and Well Written Essays - 500 words

Epidemiological studies - Essay Example An epidemiological study is the study of a population in order to determine and examine the relationship or correlation between certain segments of the population and their increased risk to disease due to expose to certain environmental exposure. This involves determining what factors related to diseases and the factors that might protect humans against the disease (Gallin, John and Frederick 15) Epidemiological studies are usually divided in two categories which are; Descriptive epidemiology which looks into a population by age group ,who gets affected by a disease, the rate and time at which the disease occurs and how often it occurs and the place where it occurs. Another one is analytical epidemiology which looks into finding out the causes of disease within a population by using cohort studies, case control studies and experimental studies giving attention to ideology. Bottom line, epidemiology largely relies on figures for finding out and quantifying the association between dis ease and the risk factors in order to establish if there is a common attendance of occurrence of certain diseases within a given geographical scope. Clinical trials on the other hand are the research studies that are carried out in order to confirm or denounce if a drug is fit for human consumption using designated or pre-defined rules.

Political Science Essay Example | Topics and Well Written Essays - 500 words - 19

Political Science - Essay Example ACH manages to avoid both human bias and analytical errors by integrating both cognitive psychology and scientific methods into its system of exploration. That notwithstanding, I hold the opinion that bringing on board other analysts when using ACH is more productive than when an analyst uses it alone. This is because having many analysts on board ensures that each situation is approached form a broad angle, thereby taking into consideration all the possible alternatives. The input of the other analysts will similarly be important in doing away with assumptions while collecting evidence against each alternative (Intelligence Reports 2013). The ideal result would be that the alternative with the least evidence against it would be accepted. Bringing on board several analysts would be challenging as handling numerous views may be mentally hectic, nonetheless, the process would be comprehensive and without pitfalls, notably because the alternatives will be competing against each other. Response to Tyler I harbor the same belief as you that the content that we have covered in this course will come in handy in ensuring that we become worldwide professionals in the field of intelligence. Taking a walk down memory lane, we all attest to the fact that intelligence has made significant strides. This is because the physical maps and marker pens that were the order of the day have been overtaken by the use of satellites and information technology (Hypothesis, 2008).

Use of Language in A View from the Bridge Essay -- A View from the Bri

Use of Language in A View from the Bridge Examine Miller’s use of language and dramatic devices in helping the audience to understand the themes of A View From The Bridge Arthur Miller is regarded as a great dramatist and he explores the life struggles of an ordinary man against authority and insurmountable odds and in ‘A View From The Bridge’ he uses many dramatic devices and enigmatic themes to help the audience understand the play. Some of the main themes are jealousy, love, law, justice and social class. The play opens with Alfieri’s thoughtful analysis of the situation in Red Hook. Alfieri is a sympathetic and an educated lawyer and ‘And when I saw him walk through my door, I knew why I had waited’ clearly shows Alfieri’s character of being a perceptive and understanding man. He speaks in a conversational style and he tells the story in a series of flashbacks and he is in control of the play. He immediately creates the atmosphere – where crime was once set in that very neighborhood. Alfieri has a mysterious role and Miller uses him as a crucial link between the characters he is also used as a narrator, commentator and sometimes a character. He talks about it being ‘better to settle for half’ and how he likes that better as, the search for absolute justice results in intolerable consequences as well as, being virtually impossible.

Short Story Sonny Blues

In James Baldwin’s, Sonny’s Blues, he uses many different symbols throughout his short story to present the overall theme of suffering to the reader. He uses symbols such as music, characters facial expressions and the presence of ice, light and darkness. In the very beginning of the story when the narrator is reading the paper and he comes across the news of his brother, Sonny, he says, â€Å"A great block of ice got settled in my belly and kept melting there slowly all day long†. (Baldwin 600) He also says â€Å"†¦it was a special kind of ice.It kept melting, sending trickles of ice water all up and down my veins, but it never got less. † (Baldwin 600) This is not the only time that the ice presents itself. It reappears when the narrator meets one of Sonny’s friends who is also a drug addict, and again later when Sonny is over for dinner with the narrator’s family. The ice that appears whenever the narrator feels an uncomfortable or pa inful situation represents how the narrator is incapable of dealing with his own emotions well. The ice also allows the reader to empathize with how the narrator feels about how his brother is leading his life.Another symbol Baldwin uses throughout Sonny’s Blues is light and darkness. Throughout the story there is a contrast of light and darkness. For example, in the first paragraph of the story, Sonny’s Blues Baldwin writes, â€Å"I stared at it in the swinging lights of the subway car, and in the faces and bodies of the people, and in my own face, trapped in the darkness which roared outside. † (Baldwin 599) This contrasts the lightness and the darkness. It demonstrates the contrast between his own suffering and the world around him and the suffering of the world.Another example of lightness and darkness Baldwin uses in the short story is when the narrator’s mother is recalling the story of the narrator’s father and his brother she says â€Å"th ere was a moon that night, it was bright like day. † (Baldwin 607) This is when the narrator’s father and his brother are having a good time and walking home. This brightness of the moon is used to represent the light, which represents all the hope and good things in life. The narrator’s mother later recalls, â€Å"he says he never in his life seen anything as dark as that road after the lights of that car had gone away. (Baldwin 608) Referring to after the narrator’s father’s brother had been hit and killed. The color of the men’s skin also represents the contrast between light and darkness. The men that killed the narrator’s father’s brother were all white and the other two men were dark skinned. This is also an example of the contrasting of light and dark. This shows how the difference of something in the same situation can both have two different results. Meaning that both the light men and the dark men were drunk. They wer e each also having fun. The situations were both similar, but the end results of each situation were very different.One of the dark men lost their life to the light men. The darkness is used to represent the tormenting and dark moments in the characters lives. The darkness however is always stabilized with lightness. Just like the dark road was stabilized with the lightness of the car lights. This light is used to signify safety and comfort, while the darkness represents the turmoil also looking to destroy that safety and comfort. Another way Baldwin symbolizes the overall theme of suffering is through the character’s facial expressions and interactions.Baldwin writes â€Å"And I watched her face as she laughingly responded to something someone said to her, still keeping time to the music. When she smiled one saw the little girl, one sensed the doomed, still struggling women beneath the battered face of the semi-whore. † (Baldwin 602) This shows that even under her â⠂¬Å"battered face† there was still a glimpse of when she was young. The narrator can see her as a young innocent little girl. This shows the reader that there is hope even in suffering. Baldwin is also trying to get his point across that even though one may suffer, the suffering will not change the past and whom you are or have become.Another example of how Baldwin incorporates the facial expressions of his characters to help promote the overall theme of suffering is when the narrator is on the subway in the first few sentences of the short story. He writes, â€Å"I stared at it in the swinging lights of the subway car, and in the faces of the bodies of the people, and in my own face, trapped in the darkness. † (Baldwin 600) This illustrates that not only does the narrator feel and see suffering inside himself and his own face, but he also sees it inside the faces of others and the surroundings around him.This also proves that the overall effect of suffering is visible to one who is suffering themselves, like that of the narrators. Baldwin also promotes the theme of Sonny’s Blues by using the presence of music. The entire short story is loaded with occasions of music. The overall title of the story even contains music. â€Å"Sonny’s Blues†, promotes the tone and theme of suffering throughout the entire story. It provides the reader with information that there will be suffering in the story. Giving them an idea of what is to come before even being read. Another example of music is Sonny’s growing love for playing the piano.The narrator states â€Å"†¦Sonny was so serious about his music and how, as soon as he came in from school, †¦he went straight to that piano and stayed there until suppertime. †, â€Å"He was at the piano all day Saturday and all day Sunday. † (Baldwin 612) This tells the reader of Sonny’s love for music. It illustrates how the music is Sonny’s safety and allows h im to not suffer. When Baldwin makes it clear to the reader that Isabel and her mother grow tired of the music, â€Å"it wasn’t like living with a person at all, it was like living with sound. And the sound didn’t make any sense to her, didn’t make any sense to any of them – naturally. (Baldwin 612) This proves that music can both heal suffering but also create it. The music for Sonny was a safety. To Sonny the music made him feel at ease and helped to subside his suffering. It wasn’t until after Sonny stopped playing the piano and his records that he began to truly feel the power of his suffering. Although the music was a medicine to Sonny’s suffering, it was the cause of suffering for Isabel and her mother. This suffering caused Isabel’s mother to snap and yell at Sonny. This caused Sonny to stop playing the piano and thus the true suffering began.Another example of suffering and music is when the narrator witnesses the meeting on the corner. He watches the battered people play their music and notices their suffering. He says, â€Å"As the singing filled the air the watching, listening faces underwent a change, the eyes focusing on something within; the music seemed to soothe a poison out of them; and time seemed, nearly, to fall away from the sullen, belligerent, battered faces, as though they were fleeing back to their first condition, while dreaming of their last. † (Baldwin 615) Showing again how music can be a safety and a rescuer to not only Sonny but others as well.By the narrator stating this it shows that it is noticeable of the change in expression music brings as it lessens the sufferings of those who play. â€Å"Sonny’s fingers filled the air with life, his life. † (Baldwin 620) Near the end of Baldwin’s story Sonny plays his music once again. To most, the music Sonny plays is merely for entertainment. But to some it is a story, Sonny’s story. As Sonny plays, the narrator notices the things his brother has been through and felt. While Sonny plays the narrator notices both his brother’s suffering as well as his own.
