What are the differences for attenuation correction for: SPECT, PET
Back
SPECT:
-correction (not analytical)
calculation of the attenuation factors for every point in the image and every projection angle
calculation of the contribution weights
(there is also another method Chang's method)
PET:
-correction (not analytical)
forward projection of the µ-map to the PET projections
calculate correction sinograms
multiplicate the measures PET-sino
-correction (not analytical)

PET:
-correction (not analytical)
