Epicardial coronary imaging using high frequency (7-12 MHz) ultrasound probes could aid the surgeon performing coronary artery bypass procedures by localizing the coronary artery segments underneath epicardial fat, identifying the site of coronary stenosis to be bypassed, evaluating the integrity of distal coronary artery, assessing the efficacy of anastomosis, and detecting anastomotic complications. While an ideal coronary imaging probe is yet to be developed, early clinical experience with vascular imaging probes applied on the coronary vessels suggests that epicardial coronary artery imaging could enhance the optimum performance of coronary interventions. Fabrication of a flexible high frequency probe that could be applied not only on the arteries on the anterior surface of the heart but also on the lateral and posterior surfaces could facilitate development of newer surgical procedures as well.
使用高频（7 - 12兆赫）超声探头进行心外膜冠状动脉成像，可通过定位心外膜脂肪下方的冠状动脉节段、识别拟搭桥的冠状动脉狭窄部位、评估冠状动脉远端的完整性、评估吻合术的效果以及检测吻合口并发症，辅助外科医生进行冠状动脉搭桥手术。虽然尚未开发出理想的冠状动脉成像探头，但将血管成像探头应用于冠状动脉的早期临床经验表明，心外膜冠状动脉成像可提高冠状动脉介入治疗的最佳性能。制造一种不仅可应用于心脏前表面动脉，还可应用于侧面和后表面动脉的柔性高频探头，也有助于开发更新的外科手术。
