1. A method of computer aided visualization and diagnosis comprising: acquiring an OCT dataset using a processor in conjunction with an imaging system; evaluating the dataset, with the processor, for flow information using amplitude or phase information; generating a matrix of voxel values, with the processor, representing flow occurring in vessels in the volume of tissue; performing volume rendering of these values, the volume rendering comprising deriving three dimensional position and vector information of the vessels with the processor; displaying the volume rendering information on a computer monitor, including generating depictions of the vessels; and using morphologic and reflectivity data in the assessment, including connectivity of voxels and feature characteristics, to classify the vessels.
