(a) Schematic for the operation of the prototype dual frequency transducer. The arbitrary waveform generator (AWG) (Sony Tektronix) was triggered to send 512 low-frequency pulses through the RF amplifier (RFA) within each frame of image data by the Vevo770 line trigger. (b) A diagram displaying how the two confocal elements were constructed within the RMV probe scanhead.
