Simultaneous electronic and small format photofluorographic angiography.

Monitoring the image on the television screen during photofluorographic angiography is frequently difficult due to the short exposure times. A disk recorder has been integrated with a 100mm rapid-sequence photofluorographic camera for use during selected angiographic procedures. Each flashing image is automatically recorded on the disk recorder and is then immediately replayed during the interval between exposures. It is these considerably longer, although minimally delayed images, that are viewed during the study instead of the short live image. “Panning” to follow the progression of the contrast bolus is facilitated. The recorded angiographic series may be instantly replayed in stop motion for immediate review.
