Abstract(in English) | A surgical method to repair rotator cuff tear is decided by a tear form. To diagnose the tear form, we previously proposed a method to reconstruct 3-D shoulder rotator cuff shape from a region manually segmented by an orthopedic surgeon. However, the reconstructed 3-D shape was strongly dependent on the segmented region. Therefore, this paper proposes a method for semi-automated segmentation of rotator cuff in MR images. A rotator cuff’s statistical shape model (SSM) is utilized for the segmentation. The SSM has been constructed by applying principal component analysis to normalized rotator cuff region. The shape parameters of SSM has been estimated from MR image signals to segment the region. The mean segmentation accuracy calculated by Dice coefficient was 0.683, and the mean error distance was 2.307 mm. |
