Title: Can you improve CT coronary arteriography?

Speaker: Kevin Johnson, Yale Diagnostic Radiology

When/where: Tuesday, Jan 25th, 4:15PM AKW 200

Abstract: 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 does 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?
