Overview
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 clinic as standard care.
Eligibility
Inclusion Criteria:
- Patients with a chronic wound on the foot that is presumed to be due to arterial insufficiency.
Exclusion Criteria:
- Patients with a massive deep tissue infection.
- Patients with preexisting skin conditions, such as melanoma, psoriasis, in areas close to the wound(s).
- Noncompliant patients who do not adhere to care plans.
- Pregnant women.
- Adults unable to consent.
