Description
Summary:SPRINT (Single Photon RINg Tomograph) is a multiple detector single photon ring imaging device for radionuclides developed at The University of Michigan. The device employs a circular ring coded aperture to minimize mechanical motion while maximizing photon efficiency. A one dimensional pseudorandom coded aperture is used that provides transverse section tomography of the human head. 78 detector locations are equally spaced around the ring. Gamma rays incident upon the NaI(Tl) detectors are energy selected and counted by a microprocessor controlled data acquisition chain. initial calibration has begun with the use of a partially filled ring of 48 detectors.
