MCAT--a multimedia cardiac angiogram tool.

In this article, we present the prototype of the Multimedia Cardiac Angiogram Tool (MCAT). The MCAT provides capabilities for reviewing angiograms recorded at a cardiac catheterization laboratory. A doctor can use MCAT to annotate angiograms with audio, text, and graphics. He/she can selectively package the annotated multimedia angiograms into a document, save it as the record for the visit or use it for case presentations, or send it to another doctor over a network. MCAT streamlines data collection at a cath lab and is intended to improve the efficiency of communication and collaboration between doctors. This paper describes the design, implementation, and future directions of the prototype.
