摘要： A repolarization system including an ultrasonic probe includes a plurality of transducers, a voltage generator, a switch, a connector, an interface, and a controller. The plurality of transducers are provided in the ultrasonic probe. Each one or more of the transducers is provided with a pair of electrodes. The voltage generator is configured to generate a predetermined voltage high enough to repolarize the transducers. The switch is configured to switch to supply the voltage to the pair of electrodes. The connector is configured to connect the pair of electrodes to the switch through a plurality of lands. Each of the plurality of lands corresponds to the pair of electrodes. The lands are provided to keep insulation enough to repolarize the transducers among the lands. The interface is configured to give an instruction. The controller is configured to control the voltage generator to generate the predetermined voltage. The controller is further configured to control the switch to supply the predetermined voltage to the pair of electrodes in accordance with the instruction.
