Abstract
We explore the feasibility of using photoacoustic imaging based on a focused transducer to characterizing acute myocardial ischemia at different stage. In this study, we blocked rat left anterior coronary descending artery (LAD) to induce the acute myocardial ischemia. The results show that the intensity and areas of photoacoustic images of myocardial decrease with the LAD time increasing, which suggests that photoacoustic imaging has a potential for diagnosis of acute myocardial ischemia.
