Abstract

The television camera comprises an important link in the imaging chain of digital subtraction angiography equipment. Various factors including spatial resolution, signal to noise ratio (SNR), progressive and interlaced read out, exposure utilization and camera lag are investigated. Requirements for the video camera for optimized DSA studies include sufficient bandpass to satisfy digitization matrix sizes, an 800:1 camera SNR, progressive read out of the camera target, and bias light to minimize build-up lag response.
