Abstract:Photodynamic therapy (PDT) is a minimally invasive method for treating oral leukoplakia. In this paper, we propose a portable PDT device consisting of a flexible circuit board with a liquid flow cooling module on the back. The light source size was 17[Formula: see text][Formula: see text][Formula: see text]mm, and the irradiation area of the light source was up to 100[Formula: see text]mm2. The irradiance range of this device was from 10[Formula: see text]mW/cm2 to 100[Formula: see text]mW/cm2. Simulation and … Show more
