치과 파노라마 X-ray 영상으로 골다공증 여부 확인

Summary #

Dental Panoramic radiographs (DPRs)는 하악골의 조직/모양 특징을 통해 골밀도 추정을 위한 정보를 제공한다. 680 사례에 대해 CNN으로 이를 추정함. (고대안산병원 2009~2018)

4가지 모델을 확인함

  1. CNN3
  2. VGG-16
  3. VGG-16_TF (transfer learning)
  4. VGG-16_TF_FT (fine tuning) --> AUC 0.858

추가로 gradient-weighted class activation mapping 기술로 가시화 함
