Real time b mode ultrasound quality control test procedures. Unlike a mode b mode is based on brightness with the absence of vertical spikes. It is capable of operating in a variety of imaging and therapy modes on transmit and continuous receive on all array elements even during high power operation. There is no y axis on b mode instead there is a z axis which represents the echo intensity or amplitude.
