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.

For transformerless switching regulators, a current-mode controlled boost converter operates based on current sensing through a switch to ground, allowing use of common controllers. To avoid reverse current from a cascaded charge pump, the input of the charge pump is blocked by a diode from passing through the switch to ground and is itself separately switched to ground.

A reversible transducer connector allows the connector to be inserted within the receptacle in more than one orientation. The electrical connections between the receptacle and connector are reprogrammed based on the orientation. The connector is inserted in two or more stages, such as using zero-insertion or magnetic retention in a first stage to identify the connector and using an automated engagement to engage remaining channel connections in a second stage for use. Doors for protecting the connector and/or receptacle may be opened and/or closed magnetically.
