METHOD AND SYSTEM FOR RECOVERING SCINTILLATION PULSE INFORMATION

摘要

A method for recovering scintillation pulse information. The method comprises the steps: obtaining a scintillation pulse database of unstacked compliance single-events in a low count, and establishing a noise model of a scintillation pulse for the scintillation pulse database of the single-events; calculating a posterior probability logarithm value of a specific energy value according to the noise model of the scintillation pulse; and repeatedly calling the second step by means of calculations, and obtaining an energy value meeting a maximum posterior probability condition. A system for recovering scintillation pulse information. The system comprises a fluctuation model module, a posterior probability module, and an energy value search module. The method and system for recovering scintillation pulse information in the present invention effectively improve the precision of a system energy calculation, and is specifically suitable for an energy calculation of a sparse quantization level ADC digital nuclear instrument.
