title: On-line 3D evaluation of left ventricular wall motion in magnetic resonance imaging.
abstract: In the present research a system for medical image processing has been proposed, which allows dynamic 3D visualization and successive left ventricular wall analysis. The 3D volume rendering algorithm results are presented using a friendly Graphical User Interface (GUI) giving the possibility to change interactively image processing and visualization parameters at any step, to perform simple and effective image manipulations. The left ventricular wall detection algorithm is based on the evaluation of classified volumetric data during volume rendering algorithm. In fact classification operation includes a 3D segmentation. The system has been tested in medical environment, for Magnetic Resonance (MR) images. Resulting studies have demonstrated a very high global efficiency in practical situations by using typical data volume dimensions.
