  Purpose

Researcher at Beckman Laser Institute have developed many non-invasive imaging modalities for evaluation of skin blood flow. In this study the researcher can use Multi-Spectral Imaging and Laser Speckle Imaging device during Vascular Occlusion on the skin.

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 dynamics that these instruments are designed to sense.

Primary Outcome Measures:
  • Multi-Spectral Imaging (MI) and Laser Speckle Imaging (LSI) [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    The MI/LSI devices can determine changes in skin tissue and skin blood flow during skin occlusion


Estimated Enrollment: 20

Estimated Study Completion Date: November 2016
Estimated Primary Completion Date: November 2016 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Multi-Spectral & Laser Speckle Imaging
Multi-Spectral & Laser Speckle Imaging
Device: Multi-Spectral & Laser Speckle Imaging
Changes in skin tissue and blood flow.
Other Name: Multi-Spectral & Laser Speckle Imaging

Detailed Description:

The primary reason for including pressure cuff occlusion in this protocol is to test the performance of MI technologies in the full range of vascular conditions ranging from ischemic (under-perfused or unsaturated) to hyperemic (over-perfused and over-saturated).
