摘要
The reconstruction of artifact free images is made possible by the implementation of a SPECT imaging device that employs helical scanning. The SPECT imaging device includes a detector configured to detect photons, such as photons, that are projected onto it. A collimator is axially aligned with the detector and includes a plurality of pinholes configured to create overlapping projections of the photons. An object support structure is configured to move in a direction that is axially aligned with the detector and collimator. The detector and collimator are configured to rotate around the object support structure in a transaxial plane to the object support structure while the object support structure moves in an axial direct to the collimator and detector.
