This is a design paper describing a 4 dimensional processing and display system for cardiovascular research. A 4 dimensional image in this paper refers to a time (or other) series of 3 dimensional images. The system consists of components to develop, test and run programs and to manipulate and store multidimensional digital images. A 4 dimensional display is used to study raw and processed data. The display uses binocular stereo to generate a 3 dimensional image and bulk memory to store multiple stereo pairs for the fourth dimension. Voice input and output will be used to communicate with the system. A binocular infrared eye tracker will be used as a multidimensional cursor to interact with the data. Software development areas are summarized. The current state of the project is presented at the end of the paper. An up to date summary of progress will be presented at the conference.
