Abstract: An ultrasound diagnostic apparatus according to an embodiment includes image processing circuitry. The image processing circuitry acquires, based on a result of ultrasound scanning performed on a subject, blood flow information including a value that indicates a blood flow at each position within the subject and tissue property information including a value that indicates tissue properties at each position within the subject. The image processing circuitry generates a first image in which a difference in value in the blood flow information is represented by at least a difference in hue and a second image in which a difference in value in the tissue property information is represented by a difference other than the difference in hue. The image processing circuitry generates a combined image by combining the first image and the second image.

Abstract: An ultrasound diagnosis system according to an embodiment includes processing circuitry. The processing circuitry generates two or more images derived from image processing performed on an ultrasound image relating to a subject. The processing circuitry generates two or more adjusted derived images by applying variable coefficients to each of the two or more derived images. The processing circuitry generates a synthesized image of the ultrasonic image and the two or more adjusted derived images.

Abstract: An ultrasound diagnostic apparatus according to an embodiment includes a processing circuitry. The processing circuitry acquires first image data that is image data obtained during the ultrasound scan executed on the object and that is image data before the coordinate conversion corresponding to the format of the ultrasound scan. The processing circuitry uses the trained model generated through the learning using the first image data obtained during the previously executed ultrasound scan and the area including the object in the first image data to estimate the area in the acquired first image data.

Abstract: A medical image diagnostic system according to an embodiment includes a first device, a second device, a communication unit, a first detection circuit, a second detection circuit, and a control circuit. The first device acquires a first signal to be used for diagnosing a subject, acquires a second signal from the first signal, and outputs the first signal or the second signal. The second device includes a generation unit that generates image data by using the first signal or the second signal. The communication unit establishes communication between the second device and the first device and transfers the first signal or the second signal to the second device. The first detection circuit detects a diagnostic status from the first device. The second detection circuit detects a communication status from the communication unit. The control circuit controls at least one of the output from the first device and a communication speed of the communication unit on the basis of the diagnostic status and the communication status.

Abstract: An ultrasound diagnosis apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to generate an ultrasound image on the basis of a result of an ultrasound scan performed on a region including a part of a subject. The processing circuitry is configured to obtain a schematic image schematically indicating the part of the subject. The processing circuitry is configured to cause a display to display the schematic image and either the ultrasound image or an image based on the ultrasound image, in such a manner that the orientation of the subject included in either the ultrasound image or the image based on the ultrasound image and the orientation of the subject indicated in the schematic image are close to each other, on the basis of an analysis result from an analysis performed on either the ultrasound image or the image based on the ultrasound image.
