Abstract
The potential of a research prototype Kinestatic Charge Detector and data acquisition system for megavoltage portal imaging is discussed. Monte Carlo modeling of, and experimental results for, the line-spread function, modulation transfer function, energy efficiency and quantum detection efficiency are given and compared with those of portal film detectors. The first phantom images from the small-field system are compared with images of the same phantoms taken with commercial portal film systems. Future directions are discussed.
