Abstract:
1. An apparatus for sonicating a patient, said apparatus comprising: an ultrasound array having a plurality of transducers; a driving module for driving said transducers; a control kernel configured to cause said driving module to drive said transducers concurrently at two different frequencies, wherein the control kernel comprises: a master microcontrol unit and a plurality of slave microcontrol units, each of said slave microcontrol units configured to control a subset of said transducers, wherein said master microcontrol unit provides instructions to said slave microcontrol units; and a dual stage voltage controlled oscillator/phase locked loop (VCO/PLL) circuit comprising: a first stage that receives a waveform having a first particular frequency and scales that first particular frequency by a first scale factor, and a second stage that receives a waveform having a second particular frequency and scales that second particular frequency by a second scale factor.
