    摘要: A method of treatment by ultrasound comprises providing a first, ultrasound field intensity-to-voltage transducer sized for insertion into the vicinity of a treatment site and a second ultrasound treatment transducer. The free field intensities created by the second transducer in response to various second transducer exciting signal levels are determined. The first transducer outputs in the free field in response to various second transducer exciting signal levels are also determined. The first transducer is inserted into the vicinity of the treatment site, and the second transducer is positioned to create an ultrasound field at the treatment site. The distance from the second transducer to the first transducer is determined. An exciting signal is applied to the second transducer. The output of the first transducer is determined. The level of the exciting signal applied to the second transducer, the determined distance and the first transducer output are employed to determine the attenuation coefficient of the tissues between the second transducer and the first transducer.

    摘要: A method of treatment of tissue with focussed ultrasound comprises placing adjacent the tissue to be treated a reflector of ultrasound or an ultrasound energy conversion device which converts received ultrasound energy to heat, stores the heat and then releases the heat over time into the tissue to be treated. An ultrasound transducer is then oriented with its focal point adjacent the reflector or ultrasound energy conversion device. The tissue is then irradiated with high intensity focussed ultrasound while the reflector or ultrasound energy conversion device is in place.

    摘要: A heat-sterilizable ultrasonic surgical scanner includes an ultrasonic transducer and a permanent magnet motor for moving the transducer along an arcuate path. The scanner further includes a housing for the ultrasonic transducer and the motor. The housing includes an acoustically transparent window for transmitting ultrasonic energy from and into the housing. A resilient diaphragm permits expension and contraction of a coupling fluid with which the housing is filled without causing fluid loss from the housing due to leakage. The resilient diaphragm is mounted at a location remote from the acoustically transparent window.

    摘要: An ultrasound brain lesioning system with ultrasound, CT or MRI site localization includes a skull fixation apparatus, a position data translating fixture and a computer-controlled ultrasound transducer. The skull fixation apparatus is utilized in combination with ultrasound, CT or MRI scan transparencies and with a digitizing tablet in order to transfer transparency data both as to skull fixation benchmarks and tumor locations into a computer. The transducer is cooperatively arranged with the translating system such that the benchmarks of the skull fixation apparatus are utilized to derive X, Y and Z linear coordinates and two rotary coordinates which are at right angles to one another which are also input into the computer such that the computer is then capable of automatically driving the transducer and positioning it at the appropriate location for producing volume lesions in the brain at the site of the identified brain tumors or other selected tissues.
