SPECT with MPH collimators of a Derenzo-type hot rod phantom. Transaxial SPECT image (right) of a Derenzo-type hot rod phantom (left) filled with 123I solution that was acquired with the MPH collimators using the same acquisition protocol and the same reconstruction parameter settings as for clinical DAT-SPECT except that attenuation correction was not performed. The red circles overlaid to a CT image of the phantom (middle) illustrate that the distance between neighboring rods equals their diameter
