Influence of the effect pf partial volume and the image filters in the removal of double-phase PET images

A procedure of evaluation for PET studies of double-phase has been developed, and has been achieved to validate this procedure about images of mannequins for which the quantitative outcome was known to get. He has been also evaluated the effect of filtering on these images. You can reach the conclusion that the best results are obtained making the image ratio, making asymmetrical filtering of images. Since this filtering manages to reduce the partial volume effect, it is useful in assessing increases in recruitment in regions of reduced size, on double-phase PET studies. (Author)
