Abstract
This poster provides detail of the radiation doses patients are exposed to in computed tomography (CT). CT helps give radiologists a more detailed image of patients. With CT first coming in the United States in the 1970s the usage has increased every decade. Presently over 100 million CT examinations are done annually. With increased usage some patients are being overexposed by scanners. A study done in the late 2000s found patients received up to eight times the radiation needed. Incidents such as this caused the need for imaging campaigns to be launched by the American Society of Radiologic Technologists to safely radiate patients. Different imaging procedures of the same area of interest can be done that cause different amounts of radiations. Different amounts of radiation to the patient can range depending on the exam. X-ray has much lower radiation doses then CT. Scanners now can still give too much radiation. Research found this can be two to three times more radiation then needed. CT is responsible for 2% of new cancer cases each year. This equals about 36,000 cases yearly.
