Development of a variable-radius pinhole SPECT system with a portable gamma camera.


OBJECTIVE To develop a small-animal SPECT system using a low cost commercial portable gamma camera equipped with a pinhole collimator, a continuous scintillation crystal and a position-sensitive photomultiplier tube. MATERIAL AND METHODS The gamma camera was attached to a variable radius system, which enabled us to optimize sensitivity and resolution by… (More)
