The DMR - BrainVoyager Diffusion Weighted Project File is a program used by medical professionals in the process of analyzing MRI data from MRI brain scans. The DMR - BrainVoyager Diffusion Weighted Project File was designed and developed by BrainVoyager for the purpose of describing the brain imagery that is captured during an MRI scan. The actual data is not stored or contained in the DMR, the DMR file is simply the file program used to translate the data. The actual data is stored in one or more corresponding files. This program is frequently used for concatenating multiple images.
