Unsupervised 3D Prostate Segmentation Based on Diffusion-Weighted Imaging MRI Using Active Contour Models with a Shape Prior
Figure 8
3D segmentation results of three patients. The first row is the manual segmentation by an expert human reader, and the second row is the automated segmentation by proposed method. The prostate specimen corresponding to the first column weighs 45 g and measures 4.5 cm superior to inferior (SI) × 4.0 cm medial to left (ML) × 3.2 cm anterior to posterior (AP), the prostate specimen corresponding to the second column weighs 72.1 g and measures 5.5 cm SI × 5.0 cm ML × 3.6 cm AP, the third column's prostate specimen weighs 56.3 g and measures 4.5 cm SI × 5.0 cm ML × 3.2 cm AP.
