  2. SPECT camera Infrared Tracking System Awake Animal SPECT-CT Imaging System An awake mouse with infrared reflectors for head tracking shown in imaging burrow. Computer display illustrating real-time pose tracking via the stereo infrared CCD cameras.

  3. SPECT Data Acquisition System Modifications • Accommodate analog signals from two gamma cameras • Need to incorporate time stamp event by event • Software controlled high voltage to gamma cameras • Elimination of long signal wires by employing fiber optic USB2 repeater SPECT camera SPECT camera data and voltage cables
