Single photon emission computed tomography using multi-slice fan beam collimators


Journal Article (Academic article)

Collimators have been built and evaluated for a SP/ECT system, consisting of two opposing LFOV scintillation cameras and a gantry, which have parallel collimation along the cranial-caudal axis of the patient and converging collimation in a direction perpendicular to this axis. A fan beam convolution algorithm reconstructs the transverse slices and provides partial compensation for γ-ray attenuation. It is concluded that the fan-beam collimator system, when compared to the conventional parallel-hole collimator system, produces simultaneous improvements in SP/ECT system sensitivity and resolution
