Abstract

An ultrasonic diagnostic apparatus includes a wireless communication unit and a control unit. The wireless communication unit is connected to a communication line via a wireless relay device, communicates with an information terminal via the communication line, and transmits ultrasonic image information to the information terminal. The control unit selects a shared group ID, which is one of a plurality of registered group IDs registered in advance, according to an operation of a user. The control unit, together with the wireless communication unit, transmits the shared group ID to the wireless relay device. The wireless relay device receives an affiliated group ID from the information terminal to establish wireless communication with the information terminal for which the affiliated group ID matching the shared group ID is received.
