However, bias error arises in the case of diffuse transmission measurements because the scattered radiation originating at the sample is not distributed uniformly over the surface of the integrating sphere and the radiation sensed by the detectors includes the first reflection of this non-uniform distribution.
Historically, grid-less imaging resulted in scattered radiation, causing a significant loss of image contrast, making it difficult for radiologists to make an accurate diagnosis.
where Is represents the intensity of scattered radiation and It represents the intensity of radiation transmitted in the same direction as incident light.
