1. A method of generating, with a processor, a segmented image of a subject based on a number of magnetic resonance (MR) images of the subject, the method comprising: generating values on an absolute scale of at least two parameters indicative of tissue type in the number of MR images for each pixel/voxel of the number of MR images, wherein the absolute-scale values are independent of MR scanner settings, and segmenting the generated absolute-scale values of the pixels/voxels in the number of MR images according to tissue type; and generating, by the processor, the segmented image of the subject, in a viewable form, based on the segmented absolute-scale values.
