Quantification of posterior fossa structures in fetal brain MR images

摘要

This paper describes results for an ongoing research on the segmentation of the posterior fossa and the structures it contains in fetal brain MR images. A semi-automatic segmentation algorithm based on Dijkstra's algorithm and a fast marching level set method is suggested. The algorithm has been tested on a small number of images and compared to manual segmentations done by experts. It shows reasonable results, but a more elaborate study with more data is needed to statistically evaluate the proposed algorithm.
