Noise spatial nonuniformity and the impact of statistical image reconstruction in CT myocardial perfusion imaging
Purpose: To achieve high temporal resolution in CT myocardial perfusion imaging (MPI), images are often reconstructed using filtered backprojection (FBP) algorithms from data acquired within a short-scan angular range. However, the variation in the central angle from one time frame to the next in ga...
