Computed Tomography Test for Capturing 3D Images
Computed tomography is a specialized X-ray imaging technique that employs computer processing to snap shots and to present a three-dimensional (3D) model of whatever is being imaged. The digital geometry processing is used to produce the 3D images of the internal structure of the object. During the Computed tomography test, a large series of two-dimensional X-ray images are taken around a single axis of rotation.
Computed tomography test is a non-invasive and painless treatment procedure that uses highly specialized kind of X-rays to generate suitable images of the bone structure, soft tissue, internal organs and blood vessels. During the test, the patient is required to lie down on a narrow examination table that slides into a chamber which performs X-ray of the entire body. A source of x rays rotates around the inside of the circular opening and produces narrow, fan-shaped beam of x rays. Often doctors use a "contrast material" to enhance the visualization of the internal structure. The images produced can be examined on a computer monitor.
Computed tomography test is useful for determining the anatomy and structure of bones and organs. This test has wide applications including detection of brain injury, skull fractures, soft tissue, blood vessels, brain tumors and blood clot. Radiologists can diagnose diseases like cancer, infectious disease, musculoskeletal and cardiovascular diseases.
Although this medical test is safe to use, some side effects such as allergic reaction to the intravenous contrast material, itching, skin rash have been observed. The benefit of this test far outweighs the risk.
