The display of 3D MRI data with non-linear focal depth cues

Three-dimensional (3-D) data is typically complex, and focusing is studied as a way to declutter the magnetic resonance image (MRI) so that detail may be seen in the spatial context of the entire cube of data. The first focus algorithms implemented linear focus where a plane of sharp focus was passed through a cube of data in much the same way that an optical lens views real samples in a microscope. Since most structures of biological interest are not planer, nonlinear focus is implemented where an entire non-planar object(s) may be presented in focus
