Paper Abstract

The authors developed and clinically applied digital radiographic facilities suitable for general examinations based on x-ray image intensifier/video systems. Digital imaging permits instantaneous production of images on a monitor which can then be visually evaluated and processed to optimize image quality prior to selection for permanent hard-copy. We think of this system as a multi-modality digital 100 mm camera to replace the universally accepted 100 mm or 105 mm photofluorographic images. The requirements for a digital 100 mm camera are a digital system which can operate effectively at 100 mm or less exposure levels and 100 mm exposure times so as to consistently provide low noise and stop all motion. It has previously been shown that 10242 digital matrices provide adequate resolution for 9 - 10' fields of view and permit the same quality as is used for the gold standard 100 mm photofluorography. Here we investigate whether large field sizes (16') can benefit by increasing the matrix to 20482.
