Abstract

In today’s world of rapidly changing medical technology, it is important to maintain quality diagnostic information for medical professionals. However, it is equally important to minimize patient and personnel radiation exposure risks. Helical (spiral) computed tomography (CT), was one of the most significant developments in the field of radiography. This article will review the evolution of CT and the corresponding quality assurance program requirements; including quality control tests, and the test tools used to follow the guidelines set forth by AERB. These guidelines must be maintained by medical facilities across the country in order to continually provide patients the quality medical information they expect, and minimum radiation dose they deserve. CT has made rapid developments within the past 10 years, and continues to be an integral part of the field of radiologic special imaging. Quality assurance testing assures periodic performance testing of the CT scanner and comparison to standards.
