Devices, methods, and systems for providing imaging of one or more aspects of blood perfusion
The present invention relates to a device (100), system (500, 500 ', 500' ') and method for providing imaging of one or more aspects of blood perfusion caused by heart-induced blood movement in a skin area (12) of a subject. Current perfusion imaging systems use photoplethysmography (...

| description | The present invention relates to a device (100), system (500, 500 ', 500' ') and method for providing imaging of one or more aspects of blood perfusion caused by heart-induced blood movement in a skin area (12) of a subject. Current perfusion imaging systems use photoplethysmography (PPG) or speckle contrast (SC), but the problem of both techniques is that there is considerable ambiguity since the signal source (volume pulsation in PPG or blood flow in SC) is unknown. The invention is based on the idea of combining two different types of measurements (i.e., wide-field imaging and radial imaging) in order to estimate the source depth (20) of the signal to provide more accurate PPG and SC imaging.
本发明涉及一种用于提供由对象的皮肤区域(12)中的心脏引起的血液运动引起的血液灌注的一个或多个方面的成像的设备(100)、系统(500、500'、500")和方法。当前的灌注成像系统使用光电体积描记术(PPG)或散斑对比(SC)，但是两种技术的问题是存在相当大的模糊性，因为信号源(PPG中的体积脉动或SC中的血流)是未知的。本发明基于组合两种不同类型的测量(即，宽场成像和径向成像)以便估计信号的源深度(20)从而提供更准确的PPG成像和SC成像的想法。 |
