Title: RADIATION DETECTION APPARATUS AND METHOD, AND DATA PROCESSING METHOD AND PROCESSORS
Abstract:
A radiation detection apparatus and method, and a data processing method and processors (103, 303, 505), relating to the technical field of radiation detection. The radiation detection apparatus comprises: a ray detector (101); a high-speed ADC (102, 302, 403, 500) connected to the ray detector (101); and a data processor (103, 303, 505) connected to the high-speed ADC (102, 302, 403, 500); the ray detector (101) converts an optical signal produced after X-ray transmission and the action of a scintillator into an electrical signal; the high-speed ADC (102, 302, 403, 500) acquires waveform data by means of electrical signal waveform sampling; on the basis of the waveform data, the data processor (103, 303, 505) determines the number of single photon signals, and then determines to use integrated signals and/or count signals for imaging. The apparatus can use the single photon detection capability of the detector (101) to determine the number of single photon signals on the basis of waveform data, and then determine to use waveform data integrated signals and/or count signals for imaging, thereby improving the radiation detection imaging quality of a detected object, and enhancing the penetration index and substance distinguishing capability of the system.
