Photoacoustic Imaging in Wound Evaluation and Treatment Guidance
State University of New York at Buffalo
Summary
This pilot device trial aims to test the feasibility of using photoacoustic images to monitor tissue perfusion and to guide post-surgical wound treatment. Through this pilot study, the investigators will test the feasibility, identify any practical issues, and acquire essential information (e.g., drop-off rate, variation in wound healing rate) to guide future large-scale studies.
Description
This pilot device trial aims to test the feasibility of using photoacoustic images to monitor tissue perfusion and to guide post-surgical wound treatment. Through this pilot study, the investigators will test the feasibility, identify any practical issues, and acquire essential information (e.g., drop-off rate, variation in wound healing rate) to guide future large scale studies. For recruited patients, wound care will be guided by both photoacoustic imaging and Kent imaging, a multi-spectral imaging technique for tissue oxygenation mapping. None of the techniques is currently used in the cli…
