METHOD OF RESOLVING PULSE PILE-UP OF RADIATION COUNTER TYPE-IMAGE SENSOR SIGNAL PROCESSING END USING ONLY DIGITAL PROCESS, PULSE PILE-UP RESOLVING DEVICE, PROGRAM AND RECORDING MEDIUM USING SAME
The present invention relates to a method of resolving pulse pile-up of a radiation counter type-image sensor signal processing end using only a digital process, which has resistance against noise, has less power consumption, and allows the design to be easily implemented only with a digital process, a pulse pile-up resolving device, a program and a recording medium using the same. The method of resolving pulse pile-up of a radiation counter type-image sensor signal processing end using only a digital process comprises: a comparator output change detection step of detecting a change in an output of a comparator, which is a pulse signal output of the comparator a C variable setting step of setting an output of the comparator as a C variable when the change in the output of the comparator is detected in the comparator output change detection step a maximum and minimum determination step of comparing variable A, variable B and variable C, which are preset according to a chronological sequence to determine whether variable B is the maximum value or the minimum value of a specific section and an energy information generation step of generating energy information using the maximum value and the minimum value of the specific section, which are determined in the maximum and minimum determination step. The comparator output change detection step or the maximum and minimum determination step is performed at least one time to induce the maximum value and the minimum value of the specific section. Accordingly, there is an effect to resolve a problem of pulse pile-up in a conventional medical device such as positron emission tomography (PET), computerized tomography (CT) or the like with a large exposure.COPYRIGHT KIPO 2017본 발명은 노이즈에 강하고, 파워 소모도 적으며, 설계 또한 디지털만으로 쉽게 구현 가능한 방법인 디지털 처리만을 이용한 방사선 계수 방식 영상 센서 신호처리단의 펄스 중첩 해소 방법, 펄스 중첩 해소 장치, 프로그램 및 이를 저장한 기록매체에 관한 것이다. 이를 위하여 비교기의 펄스 신호 출력인 비교기 출력의 변화를 감지하는 비교기 출력 변화 감지 단계 비교기 출력 변화 감지 단계에서 비교기 출력의 변화가 감지되면, 비교기 출력을 C 변수로 설정하는 C 변수
