Non-rotating transaxial radionuclide imaging

摘要

Transaxial radionuclide imaging is implemented without relative rotation between detectors and a patient by employing a collimator comprising segments sharing a common central axis, each segment having a plurality of apertures extending therethrough, wherein the segments are angularly displaced from one another about the common central axis. Embodiments include SPECT systems comprising a polygonal detector having a collimator on at least two sides thereof. Embodiments further include collimators comprising six segments, each offset by an angle of 7 to 9°.
