2 Overview 2D – 3D deform matching

3 Overview 2D – 3D deform matching FNSA : 133.25 FAV : 32.74
Bowing : 7.63 Neck Length : 41.37

4 Contribution X-ray 이미지만으로 3D shape 재구성 자동으로 clinical measurement 측정
CT에서의 측정보다 더 좋은 결과

5 Method Learning CT 3D shape PCA Clinical measurement

6 Method Optimization PCA 3D shape + Optimization Clinical measurement
X-ray

7 Method Optimization PCA Silhouette Search for Closest point
3D distance Target Silhouette Gradient descent method

8 Data 뇌성마비환자 54명의 3D shape 자동 측정 CM 직접 측정 CM CT로부터 측정된 FNSA, FAV 값

9 Experiment X-ray 대신 Silhouette 사용 Leave-one-out test SPSS 9가지 각도
2장 , coronal plane, sagittal plane Leave-one-out test SPSS Paired t-test Significance level = 0.2
