Abstract

A system has been developed to allow single frame acquisition of superior quality digitized video images. The system consists of a high-quality x-ray image intensifier coupled to a high-resolution, low-noise video system. The output video signal is fed to a digital memory having 512 x 512 pixels and 8-bit accuracy. The memory output is directly interfaced to a PDP 11/70 image processing facility to allow computer controlled acquisition of video imagery as well as real-time visualization of computer processed images. Computer pro-cessed images are returned to the memory for display. Techniques and examples of processed radiological images will be discussed, and examples shown. Additional digital memories are under construction for 12-bit dynamic range.
