本文介绍了一种由三台高速CCD摄像机组成的全景心脏成像系统，利用电压敏感荧光染料对兔心脏进行荧光成像。一个强大的，独特的机械系统，以适应三个摄像头，并适应未来的实验要求。一个统一的计算机接口被创建为这个应用程序-一个单一的工作站控制所有三个CCD摄像机，照明，刺激，和步进电机旋转的心脏。几何重建算法改编自以前的心脏成像系统。我们证明了系统的成像多态性心动过速。
A panoramic cardiac imaging system consisting of three highspeed CCD cameras has been developed to image the surface electrophysiology of a rabbit heart via fluorescence imaging using a voltage-sensitive fluorescent dye. A robust, unique mechanical system was designed to accommodate the three cameras and to adapt to the requirements of future experiments. A unified computer interface was created for this application-a single workstation controls all three CCD cameras, illumination, stimulation, and a stepping motor that rotates the heart. The geometric reconstruction algorithms were adapted from a previous cardiac imaging system. We demonstrate the system by imaging a polymorphic cardiac tachycardia.
