Performance assessment of active vs passive pixel x‐ray angiography detector systems using a bias‐corrected channelized Hotelling observer and adult patient‐equivalent experimental conditions

Purpose Electronic noise associated with passive pixel ( PP ) x‐ray angiography flat panel detectors is known to compromise fluoroscopic image quality. An active pixel ( AP ) crystalline silicon x‐ray detector with potential for reduced influence of electronic noise is commercially available. The purpose of this work was to compare the performance of the AP vs PP x‐ray angiography detectors over a detector target dose ( DTD ) range relevant for...
