METHOD FOR GENERATING SYNTHETIC ELECTRON DENSITY INFORMATION FOR DOSE CALCULATIONS BASED ON MRI

摘要

A method for generating synthetic electron density information based on an acquired magnetic resonance, MR, image stack is disclosed. The method comprises: analyzing the acquired MR image stack to automatically segment the acquired MR image stack; generating warp information for a template dataset comprising at least one template electron density information map and at least one template structure information, said generating comprising utilizing structure information of the acquired MR image stack and said template structure information in order to determine transformations bringing the template structures in spatial correspondence with the structures in the acquired MR image stack, wherein said generated warp information describes at least one transformation bringing the at least one template electron density information map in spatial correspondence with the acquired MR image stack; and forming synthetic electron density information corresponding to the acquired MR image stack based on at least part of a warped template electron density information map.
