Computer Tomography

Paper Summary:

This paper explains that, while conventional X-ray exams produce two-dimensional images, CT scans use an X-ray-sensing unit that rotates around the body and a large computer to create cross-sectional images of the inside of your body. The author points out that the paranasal sinuses, a complex three-dimensional structure, prior to the use of CAT, could only be viewed through dangerous surgery; however, now with CAT, they can be viewed by computer-aided, image-guided, endoscopic sinus surgery avoiding surgical pitfalls. The paper relates that there can be risks associated with CAT scans similar to the risks of conventional rays; however, doctors and other scientists believe that CAT scans provide enough valuable information to outweigh the associated risks of radiation.

From the Paper:

"During its brief history, advancements for computerized tomography have made great improvements in speed, patient comfort, and resolution. As scan times have gotten faster, more anatomy can be scanned more quickly and more efficiently. The extreme speed of scanning allows the elimination of artifacts from patient motion such as normal breathing. Faster scanning helps to eliminate artifacts from patient motion such as breathing or peristalsis. CT exams are even now quicker and more patient friendly than ever before. Tremendous research and development has been made to provide exceptional image quality for a diagnostic guarantee of the lowest possible x-ray dose."
