Future Challenges and Perspective

Coronary imaging and functional assessment are critical to the development of coronary interventional devices. Our understanding of coronary arteries has long evolved from 2D coronary angiography to the era of intravascular imaging. The major intravascular imaging assessment techniques currently available include IVUS, OCT, and NIRS, with different methods having their own characteristics and application scenarios. Future research directions include clearer and faster image acquisition, integration of multiple techniques, and artificial intelligence interpretation.
