Abstract
The invention relates to the use of Dirac-type autocorrelation function signals for powering multielements ultrasonic transducers used in therapeutic application in order to minimize or eliminate secondary focusing. The Dirac-type autocorrelation function signals may be generated by a pseudo random binary code.
