Abstract
(EN) The present invention relates to a method for reducing noise of an encoding aperture-based dual particle image fusion device using photoelectric absorption and the Compton scattering reaction, which determines the energy and position of a scintillation signal by using a signal processing circuit implemented with a plurality of resistors and a trans-impedance amplifier, and in particular, determines and removes a noise signal determined by the Compton scattering reaction, thereby improving an image of a location of a radiation source.
(FR) La présente invention concerne un procédé de réduction de bruit d'un dispositif de fusion d'image à deux particules basé sur une ouverture de codage utilisant une absorption photoélectrique et la réaction de diffusion Compton, qui détermine l'énergie et la position d'un signal de scintillation au moyen d'un circuit de traitement de signal dans lequel sont implantés une pluralité de résistances et un amplificateur trans-impédance, et en particulier qui détermine et élimine un signal de bruit déterminé par la réaction de diffusion Compton, ce qui permet d'améliorer une image d'un emplacement d'une source de rayonnement.
(KO) 본 발명은 다수의 저항 및 트랜스 임피던스 증폭기로 구현된 신호처리 회로를 이용하여 섬광신호의 에너지 및 위치를 결정하며, 특히 컴프턴(compton) 산란반 응에 의해 결정된 노이즈 신호를 판별 및 제거함으로써 방사선원의 위치에 대한 이 미지를 개선시키도록 하는 광전흡수현상 및 컴프턴 산란반응을 이용한 부호화구경 기반 이중입자 영상 융합장치의 노이즈 저감 방법에 관한 것이다.
