Continuous infrared imaging revealed transient changes in forearm temperature during arterial occlusion, reperfusion, and recovery in a healthy subject group. Processing the imaging data with the algorithm further revealed reactive vascular sites in the skin with rapid or delayed temperature amplification. The observed temporal and spatial diversity of blood-flow-derived forearm temperature allow consideration of thermal-imaging guided placement of skin sensors to achieve enhanced sensitivity in monitoring of skin hemodynamics.
连续红外成像显示，在健康受试者组中，前臂温度在动脉闭塞、再灌注和恢复过程中发生了短暂变化。用该算法处理成像数据进一步揭示了皮肤中具有快速或延迟温度放大的反应性血管部位。观察到的源自血流的前臂温度的时间和空间多样性使得可以考虑通过热成像引导放置皮肤传感器，以提高监测皮肤血流动力学的灵敏度。
