PROBLEM TO BE SOLVED: To estimate the propagation delay time of a biological signal supplied via a radio communication line.SOLUTION: An ultrasonic diagnostic device 100 for performing synchronous processing of image data and a biological signal supplied via a radio communication line from a biological signal measuring device comprises: a synchronous signal generation part 7 which generates a synchronous signal a synchronous signal transmission part 9 which transmits the synchronous signal to the biological signal measuring device via a first radio communication line having the first propagation delay time a biological signal reception part 10 which receives the biological signal measured by the biological signal measuring device and added with a start signal synchronized with the generation of the synchronous signal and the synchronous signal having the first propagation delay time via a second radio communication line and a delay time estimation part 11 which estimates the propagation delay time of the biological signal in the second radio communication line by using propagation delay information in the radio communication lines estimated in advance on the basis of the start signal and the synchronous signal added to the received biological signal.COPYRIGHT: (C)2016,JPO&INPIT【課題】無線通信回線を介して供給される生体信号の伝搬遅延時間を推定【解決手段】画像データと生体信号計測装置から無線通信回線を介して供給される生体信号を同期処理する超音波診断装置100は、同期信号を発生する同期信号発生部7と、第1の伝搬遅延時間を有する第1の無線通信回線を介し前記生体信号計測装置に対して前記同期信号を送信する同期信号送信部9と、前記生体信号計測装置によって計測され、前記同期信号の発生と同期したスタート信号及び前記第1の伝搬遅延時間を有する前記同期信号が付加された前記生体信号を、第2の無線通信回線を介して受信する生体信号受信部10と、受信された前記生体信号に付加されている前記スタート信号及び前記同期信号に基づいて予め推定したこれらの無線通信回線における伝搬遅延情報を用いて前記第2の無線通信回線における生体信号の伝搬遅延時間を推定する遅延時間推定部11とを備える。【選択図】 図1
