There has been growing number of MRI studies using
guinea pigs as animal models, however there has been no
automatic brain extraction algorithm available for
guinea pig brain extraction. In this study, we describe
a guinea pig brain deformable model method (GBD) based
on our previous rat brain extraction method (RBD). GBD
is a template-based approach with adjusted model
parameters compared to RBD. We validated GBD on 20
guinea pig T2-weighted images and achieved an extraction
accuracy of above 90%.
