IRTIPTA

Details and patient eligibility

About

Determination of IRTI (infrared thermal imaging) can be used to evaluate PAD patients with critical limb ischemia with different degrees of lesion.

IRTI can be used to evaluate the foot blood perfusion after percutaneous transluminal angioplasty (PTA) treatment and determine the success rate of surgery.

IRTI can be used as an effective follow-up tool for patients after surgery.
