Abstract

The capabilities of x-ray fluoroscopic imaging systems to provide large amounts of quantitative information in both clinical procedures and in a research environment has not been generally appreciated. In addition, in many instances the chain can be modified to produce single images at substantially lower patient dose than when operated in the conventional manner. Even when operated in the conventional manner, the analog video signal is capable of providing much physiological information by utilizing the techniques of video densitometry (1-5). In addition the analog signal has been processed by computer to yield quantitative data for certain cardiac functions (6-9). However, modification to single scan operation provides images with lower patient dose and with higher spatial resolution. Conversion to a digital format provides the opportunity for use of simple processing for the elimination of statistically independent noise thereby increasing precision, absolute accuracy, and gray scale sensitivity.
