D-SPECT Camera’s MPI Dose Reduction Capability Yields a Significant Decrease in Radiation Exposure The need to reduce radiation exposure to patients and medical personnel has always been Spectrum’s goal since its introduction of the D-SPECT. This next generation solid-state-digital detector technology has the unique capability to count up to 10X the speed of a conventional Anger camera thus drastically reducing imaging time (2-minute Gated SPECT study) or one can significantly reduce the injected dose and acquire slightly longer (6-10 minutes).
