An object of the invention is to provide an ultrasonic CT device in which a reflected signal or the like from an object disposed close to transducers is received, and a reception signal thereof can be received by a receiver while transceivers whose number is smaller than the number of the transducers are used. The ultrasonic CT device includes: a transducer array in which a plurality of transducers are arranged; transceivers whose number is smaller than the number of the transducers; and a transmission transducer selector and a reception transducer selector disposed for each of the transceivers. While a transmitter included in the transceiver is selectively connected to any of the transducers in the transducer array by the transmission transducer selector, a receiver included in the transceiver is selectively connected to any of the transducers in the transducer array by the reception transducer selector.

Information relevant to a state of a tissue in a subject (state information) is provided with technology reducing the amount of memory and computation necessary at the time of extracting the information. An ultrasonic wave is transmitted towards a subject, a transmission wave transmitted through the subject or a reflection wave reflected on the subject is received. A reception signal is generated on the basis of the transmission wave or the reflection wave. A tissue region candidate, of a region indicating a tissue of the subject, is set on the basis of the reception signal. State information, which is information relevant to a state of the tissue in the tissue region candidate, is calculated on the basis of the reception signal and the tissue region candidate. An ultrasonic image reflecting the state information is generated on the basis of the state information and displayed.

An object of the invention is to provide a user with information that serves as a material for determining whether an image generated by processing including a neural network is valid. A reception signal output by an ultrasonic probe that has received an ultrasonic wave from a subject is received, and an ultrasonic image is generated based on the reception signal. A trained neural network receives the reception signal or the ultrasonic image, and outputs an estimated reception signal or an estimated ultrasonic image. A validity information generation unit generates information indicating validity of the estimated reception signal or the estimated ultrasonic image by using one or more of the reception signal, the ultrasonic image, the estimated reception signal, the estimated ultrasonic image, and output of an intermediate layer of the neural network.
