Paper Abstract

The accurate quantitative assessment of variations in coronary arterial dimensions and explicit visualization of the flowing blood in vivo is fundamental to early diagnosis of occlusive vascular diseases. In Magnetic Resonance Velocity Imaging the velocity of flow is usually represented by intensity maps of the three spatial components of velocity which are difficult to use for diagnostic purposes. A technique for analysing the in vivo flow in arteries from MR imaging data is presented. This method uses a specific flow related enhancement process to extract and localize the flow field within the image which is followed by global flow analysis that reveals the underlying oriented structures of the flow field. By animation our method can provide various ways of visualizing the in vivo flow and its variation towards different vessel structures and lesions. Both lateral and cross-sectional views are animated and video tapes of the operation of the on-line animation package demonstrate the effectiveness of this diagnostic tool. 1.
