摘要： According to one embodiment, an ultrasonic diagnostic apparatus includes an ultrasonic probe, a memory, and processing circuitry. The ultrasonic probe includes ultrasonic transducers. The processing circuitry measures first reflected wave signals generated by the ultrasonic probe at a first time point. The processing circuitry stores information concerning the first reflected wave signals in the memory. The processing circuitry measures second reflected wave signals generated by the ultrasonic probe at a second time point. The processing circuitry performs correction to suppress variations between the second reflected wave signals respectively generated by the ultrasonic transducers based on the information concerning the first and second reflected wave signals.

摘要： A medical data processing apparatus according to one embodiment includes processing circuitry. The processing circuitry obtains a compressed channel of data generated by compressing a plurality of first medical channels of data defined by first domain representation and respectively corresponding to a plurality of components, via an intermediate channel of data defined by second domain representation. The processing circuitry decodes the compressed channel of data to a second medical channel of data defined by the first domain representation based on a conversion process from the plurality of first medical channels of data to the compressed dataset.

摘要： A control method for controlling data processing acquired from medical imaging modalities by using multiple data processors connected to multiple medical imaging modalities via a network. The method includes obtaining image information for imaging to be performed with an imaging modality from the multiple imaging modalities. The method also includes obtaining load information of the multiple data processors before the imaging is completed. Allocating, based on graph information generated based on the obtained load information, at least a part of the multiple data processors to processing of data acquired in imaging based on the imaging information. The control method may conclude by performing processing of the acquired data with the allocated data processing resource.

摘要： An ultrasonic diagnosis apparatus according to an embodiment includes a transmission unit, a reception unit, a generator, and a display controller. The transmission unit causes an ultrasonic probe to transmit a displacement-producing ultrasonic wave and causes the probe to transmit a displacement-observing ultrasonic wave. The reception unit generates reflected-wave data based on a reflected wave received by the probe. The generator calculates displacement at each of a plurality of positions in the scan area over a plurality of time phases, based on the reflected-wave data, determines a time phase when the calculated displacement is substantially maximum, for each of the positions, and generates image data representing positions where the determined time phases are substantially the same as each other, among the positions. The display controller superimposes an image based on the image data on a medical image corresponding to an area including the scan area.

摘要： A subject motion measuring apparatus includes at least one memory storing a program, and at least one processor which, by executing the program, causes the subject motion measuring apparatus to measure motion of a subject and output motion information related to the motion of the subject, reduce, from the motion information, an error caused by a disturbance other than the motion of the subject by using a trained model, and output the motion information in which the error is reduced. The trained model has functions of receiving a data set including the motion information with a plurality of degrees of freedom and outputting the motion information with the plurality of degrees of freedom in which the error is reduced.
