NCT07216599

Brief 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.

Outcome Measures

Primary Outcomes (2)

  • Treatment fidelity rate

    The ratio of cases received additional clinical assessment due to photoacoustic imaging results.

    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.

    12 months

Secondary Outcomes (1)

  • Recruitment rate

    12 months

Study Arms (1)

Single study arm

EXPERIMENTAL

Participants will undergo imaging using the investigational photoacoustic device.

Device: Photoacoustic imaging and multispectral imaging

Interventions

Use photoacoustic and Kent imaging devices that can image vasculature and assess tissue perfusion on the foot.

Single study arm

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with a chronic wound on the foot that is presumed to be due to arterial insufficiency.

You may not qualify if:

  • 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.
