Introduction
Backprojection is the most common algorithm used in the tomographic reconstruction of a clinical data. An everyday example of tomographic is the medical x-ray CAT scan: a person is x-rayed from various angles and the two-dimensional density of the person can be "reconstructed" by using backprojection. However, the restoration is computation consuming. Our goal is using hardware to implement backprojection algorithm thus greatly decrease the processing time.
