WebWhich setting (kVp or mAs) is the key to controlling both exposure and contrast? kVp. What are the four contributors to subject contrast? 1) tissue thickness difference. 2) photoelectric effect. 3) compton's scatter. 4) beam energy (low kVp favors increased photoelectric effect therefore more contrast) Web“The EPID dose back-projection algorithm of VERIQA RT EPID 3D will offer a double benefit. It will verify treatment delivery by using in vivo EPID measurements as well as increase efficiency in pre-treatment verification by using EPID images acquired “in air”, thus eliminating the need for phantom positioning and re-planning.”
