Ultrasound Perfusion Estimation for Assessment of Peripheral Arterial Disease

Ultrasound Perfusion Estimation for Assessment of PAD

The purpose of this study is to develop a new noninvasive tool for early diagnosis of Peripheral Arterial Disease (PAD) and use the proposed method for monitoring the disease progression and the response to interventional treatment in PAD patients.

• No history of smoking, cardiovascular disease, or diabetes.

Exclusion Criteria:

Patient volunteers:

• Patients with gangrene
• Patients having surgery or stent
• Patients with ulcer on their leg

• People considered in "vulnerable" populations.

Healthy volunteers:

• Include volunteers with BMI not more than 30
• No history of smoking
