论文摘要
当今的诊断包括脉搏血氧仪，血压监测器和温度测量等设备。这些设备在做出治疗决策时为医务人员提供了重要的信息。从脉搏血氧仪的基本效用中汲取灵感，我们为成像地下脉管系统和监测心率的强大低成本方法提供了一种方法。该方法使用现成的设备，在自由空间中设置而无需物理接触，并利用近红外波长与组织的光线之间相互作用的性质。图像处理算法从快照和以隔离距离捕获的视频序列中提取心率信息。该方法可以应用于环境光的房间中，并且与可比医疗情况相当的场景保持稳健。这项研究为基于成像系统和算法的未来诊断设备设定了平台，以进行非接触式研究点研究。
Today's diagnostics include devices such as pulse oximeters, blood pressure monitors, and temperature measurements. These devices provide vital information to medical personnel when making treatment decisions. Drawing inspiration from the fundamental utility of pulse oximeters, we present a methodology for a robust low-cost approach to imaging subsurface vasculature and monitoring heart rate. The approach uses off-the-shelf equipment, set up in free space without physical contact and exploits the nature of the interaction between light at near-infrared wavelengths with tissue. Image processing algorithms extract heart rate information from the snapshot and video sequence captured at a stand-off distance. The method can be applied in a room with ambient light and remains robust to scenarios comparable to medical situations. This research sets the platform for future diagnostic devices based on imaging systems and algorithms for non-contact point-of-care investigations.
