MInDI-3D: 3D 조건부 확산 모델을 이용한 CBCT 영상 인공물 제거

•

개요: MInDI-3D는 실제 희소 뷰 원추형 빔 컴퓨터 단층 촬영(CBCT) 아티팩트 제거를 위한 최초의 3D 조건부 확산 기반 모델로, 의료 영상의 방사선 노출을 줄이는 것을 목표로 한다. 2D에서 3D 볼륨 접근 방식으로 "InDI" 개념을 확장하여, 희소 뷰 입력을 기반으로 CBCT 볼륨을 직접 개선하는 반복적 노이즈 제거 프로세스를 구현한다. 또한, CT-RATE 공개 데이터 세트의 흉부 CT 볼륨에서 대규모 가상 CBCT 데이터 세트(16,182개)를 생성하여 MInDI-3D를 강력하게 훈련한다. 정량적 지표, 확장성 분석, 일반화 테스트 및 11명의 임상의에 의한 임상 평가를 포함한 종합적인 평가를 수행했다. MInDI-3D는 CT-RATE 가상 CBCT(독립적인 실제) 테스트 세트에서 50개의 투영만을 사용하여 보정되지 않은 스캔에 비해 12.96(6.10) dB의 PSNR 이득을 달성하고, 영상 방사선 노출을 8배 감소시키는 효과를 보였다. 더 많은 훈련 데이터로 성능이 향상됨을 보여 확장성을 입증했다. 특히, MInDI-3D는 왜곡 및 작업 기반 지표에서 16명의 암 환자의 실제 스캔에 대해 3D U-Net의 성능과 일치한다. 또한 새로운 CBCT 스캐너 형상으로 일반화된다. 임상의들은 모델이 모든 해부학적 부위에서 환자 위치 설정에 충분하다고 평가했으며, 폐 종양 경계를 잘 보존한다고 평가했다.
