Design outcomes

Primary

Measure	Time frame
To determine the safety of using photoacoustic imaging to assess lower extremity blood flow in patients with peripheral artery disease. Also, whether it is possible to evaluate lower extremity blood flow. Furthermore, we will examine whether it is possible to evaluate changes before and after treatment.	—
