The Focused Ultrasound Laboratory is well equipped with all equipment necessary for ultrasound transducer and phased array construction, tuning and characterization.
The Laboratory has equipment and experience necessary for the development of high-performance ultrasound transducers. Multiple-element PZT and piezocomposite arrays can be fabricated in-house, permitting design specifications to be optimized and tailored to the application. The fabrication process includes element dicing, electrode design and etching, transducer housing design, cabling and termination considerations, as well as integration with experimental and clinical appartus. Optimal arrays have been designed and constructed for both research and clinical application.
This RF amplifier system was designed in-house to drive phased array ultrasound applicators. This distributed-control-architecture system can be configured to work in the 0.5-1.0 MHz and 1.1-1.8 MHz frequency bands and its modular concept allows to host up to 512 channels. The amplifier array channels are based on class D/E power amplifier topology and include feedback loops to precisely control their power (0 - 60 W) and phase (0° - 360°) output. All these characteristics ensure proper operation for ultrasound arrays with varying element number and sizes.
