Abstract
A histotripsy therapy system configured for the treatment of tissue is provided, which may include any number of features. Provided herein are systems and methods that provide efficacious non-invasive and minimally invasive therapeutic, diagnostic and research procedures. The systems provided herein can include flat histotripsy arrays that provide for dry coupling to a patient without a water bath. Dual-material acoustic lenses are provided which facilitate the histotripsy array or probe having a flat coupling surface. Histotripsy transducer arrays are also provided with a conductive material embedded in a matching layer of the transducer array to provide for a high-voltage connection to the transmitting surface of the array.
Claims21
An ultrasound device, comprising:
- a flat transducer array comprising one or more transducer elements;
- a dual-material acoustic lens coupled to the flat transducer array, the dual-material acoustic lens having a flat coupling surface and comprising a first material having a first speed of sound therein and a second material having a second speed of sound therein, the dual-material acoustic lens being configured to provide an equal time of flight between the flat transducer array and a focus of the ultrasound device for any radial distance across the flat transducer array.
