Essay On Elastography

Superior Essays
Elastography is a medical imaging modality that maps the elastic properties of soft tissue. The focus is whether the tissue is hard or soft and will give diagnostic information about the presence or status of a disease. It is concerned with providing images that are related to the stiffness of the tissue. This paper will discuss about elastography and the different types as well as, the principles and components involved with elastography.
Peter R. Hoskins a Caucasian, male from United Kingdom (UK) who studied Physics at Oxford University from 1977 to1980. Began working as a trainee medical physicist in Lincolnshire (UK) for four years. In 1984 he joined the medical physics department in Edinburgh (UK). Today Hoskins is a Professor of medical physics and biomechanics at the University of Edinburgh (UK) and an adjunct Professor of medical imaging at the University of Limerick (UK). Hoskins the author of “Principles of Ultrasound Elastography” wrote this document in February 2012, in United Kingdom. He intended the audience for this article to consist of students and physicians; he also wanted the public to attain knowledge of this as well. He assumed the audience shared the same physics understanding of elastography and believed they had previous knowledge of elastography techniques.

There are two different types of elastography strain-elastography and shear wave elastography. Strain-elastography evaluates the tissue after being subjected to a force; and shear wave elastography evaluates the production and detection of shear waves. Stain elastography cannot provide an image of elastic modulus and has limitations due to depth. Shear wave elastography can provide an image and improve image quality as well as reduction of image variability. In the end, shear wave elastography is suited better for the clinical settings but still needs further

    The number of elastic fibres is increased and they are oriented vertically instead of horizontally giving the dermal layer more "spring". • The number and size of fibroblasts, cells that make collagen, are increased. • The presence of numerous chemicals that are involved in the inflammatory process show that a reparative process is going on. • Changes in the blood vessels show an increase in blood flow in the dermis, essentially feeding the reparative process. • An important part of creating this inflammatory response is the mechanical stretching of the skin cause by the negative-pressure component of the…

    Soft tissues, such as muscles, blocks less radiation and appears darker on the film.” This explains that if your body part has hard tissue, the radiation wouldn’t go through your tissue which creates a white image. On the other hand, if your body has mushy tissue, there are less radiation which creates a darker image. The third imaging technology is a CT scans (Computed Tomography), a CT scans is also called a CAT scan and it is similar to X-rays. What’s interesting about a CT scan is that it can use different angles to capture different parts of a human body to get a precise images.…

    The use of ultrasound date back to 1794, Lazzaro Spallanzani, a physiologist was the first to study ultrasound physics by deducing bats using them to navigate by echolocation. In 1826, Jean Daniel Colladon used an under-water Church Bell (early ultrasound “transducer”) to calculate the speed of sound through water to prove that sound travelled faster through water than air. Later in 1915 Paul Langevin, after the titanic sank, invented the hydrophone (1st Transucer) to detect Icebergs and submarines during WWI (Tsung). It wasn’t until…

    A pregnant woman needs her pregnancy to be monitored, so her doctor refers her to a diagnostic medical sonographer. Diagnostic medical sonographers also known as ultrasound technicians use specialized imaging equipment to produce images of a patient’s internal organs. Abdominal, breast, musculoskeletal, neurological, obstetric, and gynecologist sonographers are different types of ultrasound technicians. All sonographers place an ultrasound transducer on the part of the body that is being examined. The transducer sends high frequency sound waves to the body, these sound waves produce echoes that are ‘bounced’ back to the transducer and displayed as images on the ultrasound machine.…

    In the past few decades, sonography has made some tremendous advances. A use that not many have thought about is for astronauts in space. With longer human stays in space and prospects of long term space travel, some thought it would be a great idea to have medical imaging for the space travelers. Ultrasound was chosen because it encompasses a broad base of pathologies. In 2001, NASA integrated an ultrasound into the Health Research Facility on the International Space Station with the hopes of providing astronauts with diagnostic imaging.…

    I have chosen to write my essay on the article, “Building on the Foundation of General Strain Theory: Specifying the Types of Strain Most Likely to Lead to Crime and Delinquency” by Robert Agnew. Since I first heard of strain theory, I found it to be a fascinating concept that was easily seen in both everyday life and in the media. My favorite example of strain theory involves the plot of the television series, Breaking Bad. In the first few episodes of the show, we learn that the show’s main protagonist, Walter White, had lung cancer and may die; leaving his wife, teenage son, and (soon-to-be-born) daughter with very little to no money.…
