N2 - The use of statistical shape models in medical image analysis is growing due to the ability to incorporate prior organ shape knowledge for tasks such as segmentation, registration, and classification. Shape models are trained from collections of segmented organs. Though manual interaction during training can ensure correspondence, it also introduces bias and ruins reproducibility - automation is desirable. We present a novel shape model construction method via a medial shape representation. The automatic method is based on an iterative bootstrap method that alternates between shape representation optimization and analysis of shape mean and variations. The method is used to create a model from 46 segmented prostates with quantitatively and intutitively good results.
