Abstract :
A new method to increase blood color flow imaging sensitivity was proposed in the paper. B Mode imaging transmit voltage was decreased to weaken the influence to MI, and color flow imaging transmit voltage was enhanced with the limitation of MI to increase the sensitivity. At this time, the temperature will be increased faster than normal mode. System will auto change the operating state from high sensitivity mode to normal mode, temperature will be reduced, and skin surface temperature can´t exceed 43°C.
