Intraoperative graft patency control is obtained with dynamic infrared imaging

Published in Hematology Week, July 31st, 2006

The developed heat-transfer model allows for precise measurement of graft flow by using dynamic infrared imaging and can be applied for noninvasive graft flow estimation in beating-heart surgery.

According to recent research published in the Journal of Thoracic and Cardiovascular Surgery, "Intraoperative application of thermal coronary angiography based on dynamic infrared imaging leads to useful qualitative information concerning coronary artery bypass graft flow and anatomy. Additional quantitative flow estimation is desirable to detect graft failures. The aim of this study was to develop a heat-transfer model for quantitative flow estimation in an experimental...
