Visualisation of cardiac wall motion using MR images

Myocardial motion is a good indicator of coronary artery disease. In diagnosis relating to arterial disease and post infarct assessment it is important to view and study abnormal wall motion. In this paper we describe a Web-based visualization interface to view myocardial motion. We focus on using 4D cardiac MR images to analyze left ventricle wall motion. Using the interface it is possible to compare wall motion at different locations in the left ventricle to study abnormal behaviour. We consider our method to have a number of advantages, (i) The method uses MR datasets - which, by definition, are in 3-D and are acquired using non-ionizing radiation, (ii) The method works with any MR data set (i.e. from any scanner), (iii) Our user interface is fully Web-based and, hence, the images can be viewed at any location in the hospital
