Interactive visualization of diagnostic data from cardiac images using 3D glyphs

Abstract

This paper describes accurate methods for measuring diagnostic data in cardiology and presents new ideas on interactive data visualization with 3D glyphs to get better insight about the measured data. First, we reconstruct the 3D shape and motion of the left ventricle from cardiac images using our time-varying deformable model. Then we accurately compute ventricular volume, mass, wall thickness and wall motion in 3D or 4D spaces. The computed data are interactively visualized in a qualitative and quantitative manner and can be combined into a single glyph. Thus, glyph-based interactive visualization can encode more information and can give access to several aspects of diagnostic data at once. This perceptually easy interface is useful for many diagnostic and patient monitoring applications. © Springer-Verlag Berlin Heidelberg 2003.
