Abstract

Photo-mediated Ultrasound Therapy (PUT) is a novel anti-vascular and agree-free technique, which can selectively remove blood vessels by promoting cavitation activity with a significantly lower amount of energy of ultrasound burst and nanosecond laser simultaneity when compared to energy level required by individual laser and ultrasound treatment therapies. We report the development of a high-speed PUT system with 50 kHz pulsed laser, decreasing the treatment time by a factor of 20. In addition, we combined it with optical coherence tomography angiography (OCTA) for real-time monitoring in vivo rabbit experiments. Based on quantitative prescreening and real-time monitoring of treatment response, this combination enables implementation of individualized treatment strategies.
