Abstract
An apparatus and method for therapeutic ultrasound treatment using a plurality of spaced apart piezoelectric crystals sequentially activated for a preselected time, thereby allowing the transducer containing the piezoelectric crystals to be used substantially stationary relative to the area being treated.
Claims16
A therapeutic ultrasound system adapted to substantially stationary transducer application, comprising:
- first means for generating a pulsed digital signal at a frequency in the range of greater than about 800 kHz to less than about 3.0 MHz and a spatial average intensity in the range of about 0.1 watt per square centimeter to about 3.0 watt per square centimeter;
- a sine wave filter connected to the first means and adapted to receive the signal from the first means and converting it to a second signal;
- a programmable controlling element connected to the sine wave filter and being adapted to deliver said second signal to a plurality of separate locations in a preselected sequence, each for a preselected period of time;
- a transducer having a plurality of spaced apart piezoelectric crystals each operatively connected to the programmable controlling element for sequentially receiving the second signal and delivering a pulsed ultrasound energy outwardly therefrom;
- and
- means for maintaining the transducer substantially stationary during operation thereof.
