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.
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.

RECRUITINGTreatment fidelity rate
The ratio of cases received additional clinical assessment due to photoacoustic imaging results.
Time frame: 12 months
Percentile healing score
The healing score will be defined as the ratio of the healed wound area versus the pre-treatment wound area (1-(post-treatment wound area)/(pre-treatment wound area)). A percentile healing value of 100% indicates that the wound is fully healed, while a value of 0% indicates that the wound area does not change.
Time frame: 12 months
Recruitment rate
The ratio of recruited patients to the total number of eligible patients
Time frame: 12 months
