    摘要： An embodiment of an ultrasound medical treatment system includes an ultrasound medical-treatment transducer and a controller. The controller controls the medical-treatment transducer to emit ultrasound to thermally ablate patient tissue. The control includes a control parameter. The controller changes the control parameter based on receiving an indication of an occurrence in the patient tissue of a transient, ultrasound-caused, ultrasound-attenuating effect. A method for medically treating patient tissue with ultrasound includes controlling the medical-treatment transducer with the control parameter set to a first setting, receiving an indication of the occurrence of the ultrasound-attenuating effect, changing the control parameter to a second setting based on receiving the indication, and controlling the medical-treatment transducer with the control parameter set to the second setting.

    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 method for reducing electronic artifacts in ultrasound images of anatomical tissue. At least two calibration signals are received from imaging ultrasound waves that have been reflected from different regions in anatomical tissue. A correction signal is derived from the calibration signals. The correction signal is subtracted from a signal to derive a corrected signal. An image generated from the corrected signal is then displayed. The correction signal may be derived using weighted averaging and may be updated upon receipt of additional signals. The correction signal may be initialized to zero periodically, in response to a change in the system, or at the direction of the operator.

    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.
