An ultrasound machine is disclosed that displays a color representation of moving structure, such as a cardiac wall tissue, within a region of interest on a monitor. Linear prestage drivers and pulse-width-modulated prestage drivers are both coupled to power transistors arranged in an \u201cH\u201d bridge for driving the voice coil motor. A routing controller allows the representative data to be routed over a transfer path corresponding to any other pads in the particular mode and prevents the general data from being routed over the transfer path in modes other than the particular mode. Tensioning rods extend vertically from within the lintel upwardly into the wall. The method further comprises delivering a microbubble-therapeutic compound from the ultrasound catheter to the vascular occlusion during a first treatment phase. The processing system includes: a non-volatile memory storing firmware needed by the processing system; and an NVM control interface writing and reading data stored in the NVM.
