Photoacoustic Imaging of Foot Wound

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.

Detailed 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 clinic as standard care.
