    摘要: An ultrasound medical treatment system includes an ultrasound medical treatment transducer and a controller. In one arrangement, the controller movingly controls the medical treatment transducer to emit ultrasound to thermally ablate patient tissue: 1) for a plurality of predetermined time intervals each associated with the medical treatment transducer movingly disposed at a different one of an equal number of predetermined positions, wherein a next-in-time time interval is associated with a position which is spatially non-adjacent to a position associated with a present-in-time time interval; or 2) for a predetermined time interval during which the transducer is continuously moved. Methods of the invention so control the medical treatment transducer using or not using the controller. In another arrangement, the transducer has an array of transducer elements and the controller activates different non-overlapping groups or different overlapping groups of transducer elements at different times.

    摘要: An embodiment of an ultrasound medical treatment system includes an ultrasound medical-treatment transducer and a controller. The controller powers the transducer to deliver ultrasound to thermally ablate patient tissue in vivo. In a first expression of the embodiment and/or a first method for thermally ablating patient tissue in vivo which optionally can employ the embodiment, the transducer is powered to deliver ultrasound for or beyond an in vivo treatment time which is a function of an experimentally-determined in vitro treatment time for the same ultrasound acoustic power. In a second expression of the embodiment and/or a second method, the transducer is powered to deliver ultrasound at or above an in vivo ultrasound acoustic power which is a function of an experimentally-determined in vitro ultrasound acoustic power for the same treatment time. In a third expression of the embodiment and/or a third method, the transducer is powered to deliver ultrasound at or above an ultrasound acoustic power threshold which is calculated from an equation.

    摘要: An ultrasound medical system has an end effector including a medical ultrasound transducer and an acoustic coupling medium. The acoustic coupling medium has a transducer-proximal surface and a transducer-distal surface. The medical ultrasound transducer is positioned to emit medical ultrasound through the acoustic coupling medium from the transducer-proximal surface to the transducer-distal surface. The end effector is adapted to change a property (such as the shape and/or the temperature) of the acoustic coupling medium during emission, and/or between emissions, of medical ultrasound from the medical ultrasound transducer during a medical procedure on a patient. In one example, such changes are used to change the focus and/or beam angle of the emitted ultrasound during the medical procedure.

    摘要: A system and method for medical treatment of tissue using ultrasound. The system comprises a probe having an array of transducer elements, an ultrasound waveform generator adapted to generate at least one electrical ultrasound signal, and a plurality of phase controls, each coupled to the ultrasound waveform generator and adapted to generate from the electrical ultrasound signal a phase-shifted drive signal that is coupled to an associated transducer element. The drive signal is effective to control grating lobe foci emitted by the array. The method employs the system.

    摘要: A system for temporal transmit apodization of an ultrasound transducer array. The system includes a waveform generator and an ultrasound transducer array having a plurality of transducer elements. Each of the transducer elements is driven by a signal generator that generates a periodic waveform. The duty cycle of each signal generator is determined by a predetermined setting of a duty cycle control. The duty cycle of each signal generator is calculated to achieve a desired beam profile of the transducer array, such as acoustic focusing for reducing the level of grating lobes and side lobes. Apodization is achieved by varying the effective amplitude at each array element by varying the duty cycle of the signal provided to each element.
