Abstract: Events of interest are detected within a gamma ray detection system. Characteristics of undesired signals, including a multiplicity of events within the signal, a density of events within the signal, and other aspects are determined. The signal is filtered based on its expected characteristics. A signal which does not have the expected characteristics is rejected, and an image is formed that excludes those rejected signals.

Abstract: A SPECT imaging system has at least one detector head, adapted for detecting a radioisotope emission from a patient, and a collimator, which directs said radioisotope emission towards said detector head, a movement subsystem, which moves at least one of a patient being imaged, or said detector heads, relative to the other. A controlling computer, includes a user interface receiving output from the at least one detector head, and controls said movement subsystem, said controlling computer including a user interface, receiving information said output from the detector head, and controls at least one parameter associated with the reception of information by the detector head. The controller displays information about a region of interest within a image to be determined, and automatically determines at least one recommended parameter for the scan based on said region of interest.
