Fat and water separated MRI enables non-invasive quantification of volume and fat infiltration in muscles. Manual segmentation of muscles is extremely time consuming why automatic alternatives are needed. . We have developed an infrastructure that enables a robust platform for non-rigid whole body registration where manual classifications of an anatomical structure in an image volume (prototype) may be automatically transferred to a new patient volume. The purpose of this work was to evaluate if using such multiple prototype voting procedure provides a robust automatic muscle classification. The result showed satisfying robustness in all 10 subjects using multiple prototype voting.
