Abstract
High-intensity focused ultrasound (HIFU) capitalizes on both heating and cavitation effects for the treatment of several conditions. Optoacoustic (OA) imaging has previously been shown to provide high sensitivity to temperature changes and coagulation in HIFU-ablated tissues. In this work, we demonstrate the feasibility of real-time monitoring of heating and cavitation with a hybrid optoacoustic-ultrasound (OPUS) imaging system based on a multi-segment transducer array. The OPUS results in experiments with liver tissues ex-vivo and a mouse post-mortem were validated with thermal camera measurements and with cryo-sections of the mouse. The suggested approach thus holds promise to be clinically translated.
