<p>PCT No. PCT/DE95/01805 Sec. 371 Date Jun. 20, 1997 Sec. 102(e) Date Jun. 20, 1997 PCT Filed Dec. 15, 1995 PCT Pub. No. WO96/20471 PCT Pub. Date Jul. 4, 1996An apparatus for treating a subject with focused ultrasound waves has an ultrasound transducer composed of a number of ultrasound transducer elements. Each ultrasound transducer element has a memory connected thereto in which, during operation, a bit pattern corresponding to a desired position of the focus of the ultrasound waves is stored. A control unit cyclically addresses the individual memories in parallel such that electrical signals offset in time relative to one another according to the desired position of the focus are present at the respective data outputs of the memories, and these signals are supplied to the respective ultrasound transducer elements connected to the data outputs of the memories.</p> |
