Treatment system for enhancing safety of computer peripheral for use with medical devices by isolating host AC power

An ultrasound medical system includes an ultrasound end effector and at least one non-ultrasound tissue-property-measuring sensor. The ultrasound end effector includes a medical ultrasound transducer assembly having at least one medical-treatment ultrasound transducer. The at-least-one non-ultrasound tissue-property-measuring sensor is supported by the ultrasound end effector and is positionable in contact with patient tissue.

Ultrasound medical system

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.
