Abstract:

The extraction of the brain portion of a neurological image is often necessary prior to tissue segmentation or image registration. While MR Imaging studies on the rat have gained much interest lately, an automatic and robust rat brain extraction tool is still lacking. In this paper, we present a deformable surface model-based rat brain extraction method which extends the popular human brain extraction tool (BET) by incorporating the brain geometry and MRI tissue characteristics of the rat into consideration for more robust extraction. Our method was demonstrated on T2-weighted MR images for five rats and compared with other rat brain extraction methods. Results showed that our method can reliably and robustly extract the rat brain with high accuracy (>92% volume overlap).
