개요

제한각도 컴퓨터 단층촬영(LACT)에서 누락된 각도 정보로 인한 문제를 해결하기 위해, 기존의 영상 영역에서의 방법과 달리 시노그램 인페인팅에 초점을 맞춘 새로운 방법을 제안합니다. 평균 회귀 확률 미분 방정식을 사용하는 확산 모델 변형인 MR-SDEs를 활용하여 투영 단계에서 누락된 각도 데이터를 채웁니다. 더 나아가, 지도 학습(distillation)과 인페인팅 행렬의 유사역행렬을 이용한 모델 출력 제약을 결합하여 확산 과정을 가속화하고 한 단계로 수행하여 효율적이고 정확한 시노그램 완성을 가능하게 합니다. 후처리 모듈은 인페인팅된 시노그램을 영상 영역으로 역투영하고 재구성을 더욱 개선하여 인공물을 억제하면서 중요한 구조적 세부 정보를 보존합니다. 정량적 실험 결과는 제안된 방법이 지각적 및 충실도 품질 모두에서 최첨단 성능을 달성함을 보여주며, 과학 및 임상 응용 분야에서 LACT 재구성을 위한 유망한 솔루션을 제공합니다.
