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.

桡动脉迂曲 (RAT) 可导致经桡动脉介入治疗 (TRI) 的失败率增加。在 TRI 之前，需要评估桡动脉形态 (RAM) 以排除那些患有严重 RAT 的患者，这对于提高手术成功率具有重要价值。开发了立体光声成像（SPAI）系统来检测RAT。进行了幻影和人体实验以证明 SPAI 系统的性能。结果表明，SPAI系统在评估RAM以检测RAT方面具有巨大的临床潜力，可为TRI的术前评估提供有效工具。
