Abstract

Previous studies [1-3] of the capabilities of a digital radiographic imager employing a scanning strip (slot) beam and a Kinestatic Charge Detector (KCD) have focussed on spatial and contrast resolution. This paper compares the temporal resolution of such a KCD system with that of a system employing a wide area beam and a rare-earth phosphor. The results are largely based on theoretical and computer simulations, including use of a Monte Carlo x-ray transport program, and indicate that for equal image SNR, the KCD yields significantly improved temporal resolution and lower doses than the rare-earth screen system. However, the KCD suffers from tube loading problems and long scan times for patient thicknesses approaching the equivalent of 30 cm of water.
