title: Simultaneous evaluation of wall motion and blood perfusion of a beating heart using stereoscopic fluorescence camera system.
abstract: In this study, we aimed to develop a stereoscopic fluorescence camera system for simultaneous evaluation of wall motion and tissue perfusion using indocyanine green (ICG) fluorescence imaging. The system consists of two high-speed stereo cameras, an excitation lamp, and a computer for image processing. Evaluation experiments demonstrated that the stereoscopic fluorescence camera system successfully performed the simultaneous measurement of wall motion and tissue perfusion based on ICG fluorescence imaging. Our system can be applied to intraoperative evaluation of cardiac status, leading to an improvement in surgical outcomes.
