|Condition or disease||Intervention/treatment|
|Abnormal Vascular Flow||Device: Multi-Spectral & Laser Speckle Imaging|
The primary reason for including pressure cuff occlusion in this protocol is to test the performance of Multi-Spectral Imaging and Laser Speckle Imaging can measure in the full range of vascular conditions ranging from ischemic (under-perfused or unsaturated) to hyperemic (over-perfused and over-saturated).
- .Modulated Imaging a non-contact optical imaging technology can detect the concentration of total hemoglobin, deoxygenated and oxygenated hemoglobin in absolute amounts in units of millimoles / unit volume of tissue measured.
- . Laser Speckle Imaging a non-contact optical imaging technology consists of a coherent light source, camera, and image acquisition system. This image device can measure and compare relative flow in vasculature at varied time points.
