Provided is a wireless probe including: an ultrasound reception/transmission module that receives a first power and scans a target object by transmitting ultrasound signals to the target object and receiving ultrasound echo signals reflected from the target object； a signal processing module that receives a second power, generates pulses for generating the ultrasound signals and generates ultrasound data by using the ultrasound echo signals； a wireless communication module that receives a third power and receives/transmits predetermined data from/to a medical device； a controller that controls supply of at least one of the first power, the second power, and the third power based on an operation state of the wireless probe； and a power unit that supplies or blocks the at least one of the first power, the second power, and the third power according to control of the controller. Each component included in the wireless probe may reduce power consumed by the wireless probe.
