Description

Summary

The purpose of this research is to evaluate and validate the performance of non-invasive imaging modalities for assessment of skin. A pressure cuff occlusion will be used to stimulate blood flow dynamic that these instruments are designed to sense. The researcher currently plan to assess only basic feasibility of the imaging instruments.

Official Title

A Pilot Study to Evaluate Multi-Spectral Imaging (MI) and Laser Speckle Imaging (LSI) and Multiphoton Microscopy (MPM) During Vascular Occlusion

Details

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).

  1. 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.
  2. 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.
