Abstract

The improvement of radiographic quality has been a subject of concern to physicians, physicists, and design engineers ever since Wilhelm Conrad Roentgen produced the first visual image of human skeletal structure. However, despite exhaustive attempts to define and quantify the multitude of parameters which effect the quality of the image, the final result must succumb to the subjective opinion of the radiologist. It is generally accepted, however, that patient motion, which may be voluntary, due to disease, or due to normal autonomic movement of viscera, serves to degrade radiographic quality by blurring the image. Conversely, any method which serves to reduce the effects of motion will also serve to improve image quality. The variety of methods which have been applied to reduce motion unsharpness may be grouped into three categories: 1. The use of drugs 2. Physiological Gating 3. The reduction of x-ray exposure time
