Abstract
Digital fluoroscopy is a technique in which it is possible to produce high resolution images at low contrast in a dynamic mode. In order to produce images with the desired resolution of 1 mm at 1% contrast level at T.V. frame rates using conventional broad area image receptors, an input exposure to the image receptor of approximately 1 mR per frame is required.1 Assuming a transmission of the order of 1%, this implies an input exposure to the patient of several hundred R/minute. This is much higher than conventional fluoroscopic exposure rates and is well in excess of normal cinefluorographic rates.
