Stereoscopic photoacoustic imaging of radial artery for preoperative evaluation of coronary intervention

Radial artery tortuosity (RAT) can lead to an increase in the failure rate of transradial coronary intervention (TRI). Before TRI, the radial artery morphology (RAM) needs to be evaluated to rule out those patients who have serious RAT, which has significant values in increasing the procedural success rate. A stereoscopic photoacoustic imaging (SPAI) system was developed to detect RAT. Phantom and human experiments were carried out to demonstrate performance of the SPAI system. The results show that the SPAI system has great clinical potential in assessing RAM for detecting RAT, which can provide an effective tool for preoperative evaluation of TRI.
