Filtered back projection (FBP) has been steadily used to reconstruct images from the projections. This algorithm has the benefit of being easy while having a low requirement for computing sources. However, shot noise in the uncooked information is distinguished within the reconstructed images and areas of high tracer uptake are likely to type streaks across the picture. Also, FBP treats the data deterministically—it does …
Positron emission tomography (PET) is a specialized radiology procedure used to look at numerous body tissues to establish sure conditions. PET can also be used to follow the progress of the therapy of sure situations.
