  • Publication number: 20180036558
    Abstract: An interstitial ultrasound thermal ablation applicator for conformal treatment of an inhomogeneous tumor lesion includes: a body having a longitudinal axis; and a plurality of array transducers mounted on the body, arranged side by side and having azimuth directions parallel to the longitudinal axis of the body, and having outer faces disposed in a polygonal arrangement; the plurality of array transducers having predetermined elevation dimensions defined for directing emitted ultrasonic energy to obtain a conformal volume treatment of the tumor lesions. An electronic driving method for driving an applicator having multiple independent transducer elements arranged in rows and columns includes: controlling focal parameters of each row and column of transducer elements; and controlling a contribution of each row and column of transducer elements in a manner to provide a conformal ablated volume.

  • Patent number: 9579081
    Abstract: A device for a bimodal diagnostic probe with optical and ultrasonic imaging, the probe including a main body supporting an ultrasonic transducer at its front end. The device includes a shell, an illumination mechanism mounted on a front end of the shell to light outside of the shell, and a collection or detection mechanism mounted on the front end of the shell to collect or detect an optical signal produced outside the shell. The shell includes an attachment mechanism to reversibly assemble it around the main body of the probe, with the illumination mechanism and the collection or detection mechanism mounted on the shell.

  • Publication number: 20140257262
    Abstract: An interstitial ultrasound thermal ablation applicator for conformal treatment of inhomogeneous tumor lesions includes: a body having a longitudinal axis, the body defining a hollow central channel along the longitudinal axis; and a plurality of CMUT array transducers mounted on the body, arranged side by side to form a cylindrical shape, having azimuth plans parallel to a longitudinal axis of the body, each of the plurality of CMUT array transducers having elevation dimensions predetermined to steer emitted ultrasonic waves to obtain a conformal volume treatment of the tumor lesions. An electronic driving method for driving an applicator having multiple independent transducer elements arranged in rows and columns includes: controlling focal parameters of each row and column of transducer elements; and controlling a contribution of each row and column of transducer elements in a manner to provide a conformal ablated volume.

  • Patent number: 6915696
    Abstract: A method is provided for manufacturing crossing/intersecting transducer arrays including first and second ultrasonic transducer arrays which intersect centrally of one another. Each transducer operates independently without any decrease in acoustic performance. The first and second arrays have their own independent signal electrodes, respectively disposed on the front and rear surfaces of the device. Because the arrays are built on a unique piezoelectric member, a portion of signal electrode of each array is adapted to be connected to ground in a manner permitting proper operation of the entire array. A method of forming matching layer sets incorporating electrical interconnections is also provided.
