Abstract:
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.
