PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic system including a front end (FE) device and a back end (BE) device capable of preventing a system operation from becoming unstable in a transition process from a separated state to a docking state.SOLUTION: In a separated state, an FE device 12 and a BE device 14 conduct a communication using two radio communication paths 18 and 20. By the monitoring of a radio communication state, the proximity of the respective devices is determined immediately before a docking state. Then, the two radio communications are stopped between the two devices, and the two devices are brought into a freeze state (an operation restriction state). Subsequently, when the docking state is formed, a wire communication is established between the two devices. Then, when cancellation of the freeze is input, the two devices return to a normal operation state. The two devices are once brought into the freeze state when there is a change in the state from the docking state to the separated state.SELECTED DRAWING: Figure 1 |
