Paper Abstract

The goal of developing an on-line electronic digital radiographic (EDR) system to replace conventional film-screen radiography (FSR) is important for at least two reasons. First, theoretical arguments show that EDR can have improved diagnostic quality, reduced patient dose and faster image accessibility than FSR. Secondly, the availability of EDR systems will remove the final impediment to the realization of the PACS concept inasmuch as FSR is the only major nonelectronic imaging modality left in the modern radiology department. The Kinestatic Charge Detector (KCD) has properties which make it a candidate for an on-line EDR systems-10. The KCD is a strip detector with high spatial resolution in two dimensions. However, mechanically and electronically, it operates like a one-dimensional detector. Thus, it can effectively scan on the order of 64 to 128 parallel x-ray lines simultaneously but with a 64 to 128-fold reduction in the number of actual detector cells and electronic channels. Moreover, this can be done at quantum detection efficiencies approaching unity. In this paper, theoretical calculations and experimental measurements of the performance parameters of a KCD are presented. Some of the particular parameters discussed include spatial, contrast, and temporal resolution.
