Hybrid segmentation of the hippocampus in MR images

Segmentation and visualisation of the hippocampus can assist with early detection and intervention for a number of brain diseases. This paper describes a semi-automatic segmentation approach that produces accurate results with a significant reduction in operator effort compared with manual segmentation. A Geometric Deformable Model incorporates global constraints to solve many of the problems associated with previous methods. The results of our hybrid segmentation model show a good correspondence with manual segmentation by an expert operator.
