A pixelated 3D Anger camera with light-loss compensation
- TRIUMF, Vancouver, British Columbia (Canada)
Position sensitive gamma ray detectors are used for a variety of medical, industrial, and scientific applications. The commercial development of the new scintillator lutetium oxyorthosilicate (LSO) makes practical the design of a new type of detector combining the best features of the Anger camera and the BGO block detector. A general purpose gamma ray camera has been designed and tested by Monte Carlo simulation. The design uses long thin fingers of LSO to obtain good spatial resolution at gamma ray energies from 100 keV to 100 MeV. The simulation was validated by comparing it with measurements on individual LSO fingers measuring 4x4x10mm and 4x4x75mm. Depth-of-interaction encoding, required for light-loss compensation, is obtained by a simple modification of the reflective coating of the fingers.
