Abstract

A motion video system and method for use with diagnostic imaging systems for combining the acquisition, display, and processing of digital video in real-time with physiological data indexing through the use of a mass storage device and digital motion video data compression/decompression, and for delivering video sequences of anatomy or graphical representations of physiological processes. The system comprises components or subsystems that operate to reduce the data content of the diagnostic video data using compression methods, assign physiological timing events, or physiological indexes, to pictures in sequence, create physiologically meaningful digital video loops, enhance visualization of the video data through spatial and temporal domain processing, as well as side-by-side real-time video displays, and archive compressed diagnostic video on a mass storage device.
