Paper Abstract

Kinestatic charge detector (KCD) systems have potential uses in all fields of digital radiography including chest, abdominal, vascular, peripheral, dual energy subtraction and mammography. The purpose of this study was to investigate the development of a chest imaging protocol for a full field of view KCD system with regard to the effect of significant variations in patient chest thickness and its possible influence on kinestatic electric field settings. This was investigated by optimizing the kinestatic setting for a 5 lp/mm bar pattern imaged with 0, 5, 10, 15, and 20 cm of added Lucite to simulate varying patient chest thickness. Preliminary results demonstrate that variation in kinestatic settings due to variations in patient thickness affects the kinestatic electric field setting. Since only one field setting is available per image scan it becomes necessary to either optimize kinestatic settings for an estimated average patient thickness or for the density function of the expected region of interest (ROI).
