Event description:
Coronary artery disease is the biggest killer in the developed world.
It has been difficult to detect before
a serious event occurs. For the first time a new technique, coronary
computed tomography arteriography, can directly image the coronary
arteries noninvasively. However image quality is limited by radiation
dose considerations. The goal is to clearly see and quantify the
atherosclerotic plaque burden. Can denoising techniques improve the
signal to noise ratio so that segmentation routines and physician
visual analysis are made more accurate and precise? Can you suggest
possible approaches to improvements?
