A system includes a source that rotates about an examination region and emits radiation that traverses the examination region, a radiation sensitive detector array that detects radiation traversing the examination region and generates projection data indicative of the detected radiation, and a projection data de-noiser that de-noises the projection data, wherein the de-noiser de-noises a projection based on a number of detected photons for the projection.
