| 内容記述 | Liquid Xe as scintillator has a very fast response. The scintillation light decays with 2.2 ns, and the recombination light for gamma-rays decayswith 45ns. Also,the scintillation yield is very high, comparable to that of Nal(Tl) crystals. These properties are considered to be advantageous for application to time of flight-position emission tomography(TOF-PET). From this perspsctive, a prototype for a TOF-PET system which consists of two identical liquid xenon detectors has been constructed using liquid Xe as scintillator material and its energy resorution, position resolution and the time resolution were measured. The energy resolutions of 29.9% and 32.4% and position resolution of 4.8mm and 9.4mm were obtained for the two identical detectors, respectively, and a time resolution of 650ps betweens the two detectors was obtained for 511keV gamma rays from position annihilation. The future development of liquid Xe TOF-PET is descussed. | |||||
