METHOD FOR DIGITALIZING SCINTILLATION PULSE |
摘要 |
A method for digitalizing a scintillation pulse, the method comprising the steps: acquiring a pulse database output by a detector under different energy ray irradiations (S1); sampling and quantizing every pulse in the pulse database of the step (S1), to acquire complete energy information included in the pulse (S2); undersampling and quantizing every pulse in the pulse database obtained in the step (S1), and using pulse prior information to estimate or fit energy information (S3); with the energy information obtained in the step (S2) used as standards, determining the mapping relationship of the energy information obtained by a prior information-based undersampling pulse energy acquisition method and obtained by the method of the step (S2) (S4); and utilizing the energy mapping relationship to correct the energy information obtained by the prior information-based undersampling pulse energy acquisition method (S5). By means of the solution, the energy calculation errors caused by an inaccurate pulse model in the prior information-based undersampling pulse energy acquisition method can be corrected. |
