Abstract
Because of the progress in computer technology, digital images become the main stream of medical imaging techniques. On these digital images, each voxel is composed of a cuboid at the size approximately of 1×1×5mm^3. The observed signal for a voxel is the summation of signals of different tissues inside the voxel. Because it is important to calculate the volumes of human biological tissues before and after medical treatments, this article will explain the partial-volume mixing effect, its mathematical modeling, and the application of independent component analysis to perfusion magnetic resonance brain images.
