## Abstract

A system and method for providing treatment feedback for a thermal treatment device (100) is provided. In certain embodiments, a thermal transmitter (120) is configured to apply an amount of thermal energy (104) to a target site (106), the thermal energy having a selected frequency and a selected power level for penetration to a depth beneath the surface of the skin. A thermal imager (140) is also provided, the thermal imager (140) being configured to capture thermal data and thermal images of the target site. The device may further provide a thermal display (160) configured to display the thermal images and thermal data, providing feedback to a user (201).
