Research abstract
A TWO-DIMENSIONAL PHOTON-COUNTING POSITION ENCODER IS PROPOSED FOR POSITION EMISSION TOMOGRAPHY (PET) 1. A METHOD OF CONTROLLING THE SPATIAL DISTRIBUTION OF PHOTONS FROM BISMUTH GERMANATE SCINTILLATORS, 2. THE USE OF ALL-DIGITAL PHOTON COUNTING FOR PROCESSING THE PHOTOMULTIPLIER SIGNAL, AND 3. THE USE OF PATTERN RECOGNITION TO ENCODE POSITION. THE NEW DETECTOR IS EXPECTED TO REDUCE THE COST OF THIS PORTION OF THE PET SCANNER BY APPROXIMATELY A FACTOR OF EIGHT. THE COST REDUCTION ANTICIPATED FOR A TYPICAL FOUR-RING CAMERA WILL BE IN THE RANGE OF $600,000 TO $1,000,000, WHICH IS 2040 PERCENT OF THE COST OF THE PET SCANNER. IN ADDITION TO THE POTENTIAL COST SAVINGS OF THIS NEW APPROACH, THE PHOTON DIVISION TECHNIQUE WILL ALLOW ONE TO OBTAIN 23MM POSITION RESOLUTION IN TWO DIMENSIONS.
