摘要：
A new compact gamma camera for small object imaging has been developed.It consists of a pixelized Nal(T1) scintillator array coupled to a position sensitive photomultiplier tube (Hamamatsu R2486) with a parallel-hole lead collimator.The compact camera has better spatial resolution than Anger camera.The average value of intrinsic spatial resolutions is 2.3 mm (FWHM).The overall spatial resolution (FWHM) is 3,5 and 6 mm at 0,2.5 and 3 mm SCD (source-to-collimator distance),respectively.The phantom studies with the compact camera have demonstrated that parallel-hole collimator gamma camera is a practical technique for nuclear medicine application.
