Task‐specific efficient channel selection and bias management for Gabor function channelized Hotelling observer model for the assessment of x‐ray angiography system performance

Purpose Channelized Hotelling observer (CHO) models have been implemented to assess imaging performance in x‐ray angiography systems. While current methods are appropriate for assessing unprocessed images of moving test objects upon uniform‐exposure backgrounds, they are inadequate for assessing conditions which more appropriately mimic clinical imaging conditions including the combination of moving test objects, complex anthropomorphic...
