Abstract:
1. An ultrasonic diagnostic apparatus comprising: an ultrasonic probe including plural ultrasonic transducers configured to transmit an ultrasonic beam according to drive signals and configured to receive ultrasonic echoes to output reception signals, reception signal processing units configured to generate parallel sample data based on the reception signals outputted from said plural ultrasonic transducers, a parallel/serial conversion unit configured to convert the parallel sample data generated by said reception signal processing units into serial sample data, a communication unit configured to wirelessly transmit the sample data converted by said parallel/serial conversion unit, a memory configured to temporarily store the sample data converted by said parallel/serial conversion unit, and a control unit configured to control said communication unit to transmit the sample data read out from said memory in response to a retransmission request; and an ultrasonic diagnostic apparatus main body including a storage unit configured to store the sample data of at least one frame transmitted from said ultrasonic probe, an image forming unit configured to generate an image signal by performing reception focusing processing on the sample data with respect to every one frame read out from said storage unit, a reception status detecting unit configured to detect a reception status of the sample data transmitted from said ultrasonic probe based on an error rate of the sample data, and a second communication unit configured to transmit the retransmission request to said ultrasonic probe when the reception status detected by said reception status detecting unit is not better than a predetermined level.
