Application of adaptive structures and pet detection system

One application of adaptive PET probe structure, which comprises at least two modules and a detector detecting ring for placement of the detector module, the at least two detector modules placed on the detecting ring to surround and surround the object to be detected, performance of each detector module includes intrinsic spatial resolution, temporal characteristics, energy resolution, efficiency of detection, the maximum count rate, the performance of the detector module is divided into a plurality of performance levels, the at least two modules having at least one detector probe a performance module performance level higher than the same performance level of other properties of the detector module. The present invention is different performance levels of detector modules used in combination, and to optimize the design of the detector module by arranging manner, to ensure the image quality of the finally obtained while reducing the use of the detector module performance class number, saving construction costs of the system.
