Abstract

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.

Claims8

Dependent claims

A non-invasive ultrasound treatment system for translating visualization data of a diseased site in a patient into movement data for guiding an ultrasound transducer relative to said diseased site for treatment thereof, said ultrasound apparatus comprising:

transducer control means for an ultrasonic transducer moving said ultrasound transducer relative to said diseased site;
data transfer means for converting visualization data of the diseased site into spatial coordinate data and placing said spatial coordinate data into said transducer control means;
fixation means adapted to be attached to the patient and including landmark reference elements, said fixation means enabling a spatial relationship between said patient and said reference elements to be established;
and
spatial translation means coupled to said transducer control means and designed and arranged for contacting with said landmark reference elements for establishing a spatial frame of reference for said ultrasound transducer relative to said patient and in turn relative to said diseased site.
