Essay On CAT Scan

A computerized Axial tomography scan is medical equipment used to image different regions of a human body as well as other animals with internal health problems. A CAT scan uses the idea of conventional X- ray imaging to a higher standard. Instead of just taking pictures of the different body part of interest, the CAT scan takes multiple pictures of the body at many different angles and creates a three dimensional structure of the body. This three dimensional structures show’s a complete body components starting with the bone, tissues, muscles and even vessels at organ level. This can help doctors examine each slide of skin at a time so that way they can pinpoint specific problem to specific regions and find the right solutions to various problem they encounter.

CAT scans produces X-rays which is a powerful form of electromagnetic energy. This has photons which are basically the same thing as visible light photons but with much more energy. This high energy helps it pass straight through the soft tissue in human bodies. The patient lied down on a flat surface of the machine and they are slowly moved through a mounted in a movable ring around the edges of the opening. This ring also supports an array of X-ray tube and is operated by a motor so that the X-ray tube and the X-ray detectors revolve around the body. Each revolution scans a narrow piece of the part of interest and the machine then records X-rays slices across the body in a spiral motion. The computer system varies the intensity of X-rays depending on the tissue type and optimum power and after the patient passes through the machine and has a complete body scan on area of interest the computer then puts the all the information it gathered from all the slides from differ...

...ut CAT scan successfully, there are specific requirements that need to be present. A CAT scan is typically ran by a radiologist that has extensive training on how to operate and read the result from many different types of radiological systems. They are trained to read results from test accurately and they mostly work together with other medical doctors such an anesthesiologist and surgeon to provide the best cost saving and efficient care for their patients. Before a CAT scan, you might asked remove all clothing from are to be scanned. If the area is intravenous, you may be required to drink some contrast fluids to increase clarity and visibility of area of interest. A CAT scan machine of course would be needed. This is a specialized machine shaped like a donut; as a person goes through, it automatically take numerous pictures place of interest at different angle.
