Abstract
The power supply in ultrasound imaging includes a switched capacitance. The capacitance is switched on to provide power during generation of pushing pulses for elasticity imaging and is switched off during other modes of imaging.
Claims11
An ultrasound system for elasticity mode imaging with ultrasound, the ultrasound system comprising:
- a power supply having an output;
- a switch switchably connecting between the output and ground;
- a capacitor in series with the switch, the capacitor and the switch forming a switchable path to the ground from a connection of the output of the power supply to a transmitter so that the switchable path operates on power provided as input to the transmitter, the switch and the capacitor not being in series with the transmitter and the power supply such that the switch does not switch the power supply from the transmitter, the capacitor arranged to provide additional power with the power supply to the transmitter for transmission when the switch is closed;
- and
- an ultrasound scanner configured to perform the elasticity mode imaging using the transmitter.
