An ultrasonic diagnostic apparatus, a medical imaging apparatus, a training device, an ultrasonic image display method, and a storage medium storing a program that can quickly set a region of interest on an ultrasonic image are provided. The ultrasonic diagnostic apparatus includes an ultrasonic image generation unit configured to generate an ultrasonic image of a subject, an inference unit configured to set, by using a trained model trained with a region of interest set on the ultrasonic image as teaching data, a region of interest on a new generated ultrasonic image, and a display unit configured to display the region of interest set by the inference unit along with the new generated ultrasonic image.

Ultrasonic diagnostic apparatus, medical imaging apparatus, training device, ultrasonic image display method, and storage medium

An ultrasonic diagnostic apparatus, comprising: an ultrasonic probe which scans an observation region in an object with an ultrasonic wave; and an estimated image generating unit which, by using a model having been machine-learned using learning data including first data based on a first received signal that is obtained by first transmission/reception of an ultrasonic wave and second data based on a second received signal that is obtained by second transmission/reception that represents a larger number of transmissions/receptions than the first transmission/reception of the ultrasonic wave, generates an estimated image equivalent to image data obtained by the second transmission/reception from third data based on a third received signal that is obtained by transmission/reception equivalent to the first transmission/reception of the ultrasonic wave by the ultrasonic probe.

Ultrasonic diagnostic apparatus, learning apparatus, and image processing method

An ultrasonic diagnostic apparatus includes an ultrasonic probe configured to transmit and receives ultrasonic waves to and from an observation region of an object. The ultrasonic diagnostic apparatus further includes an estimated image generating unit configured to generate estimated image data corresponding to image data based on an ultrasonic focused beam from image data obtained by transmission of an ultrasonic plane-wave beam by using a model having been machine-learned from learning data including image data obtained by the transmission of the ultrasonic plane-wave beam and image data obtained by the transmission of the ultrasonic focused beam.

An information processing apparatus includes an acquisition unit configured to acquire ultrasonic image data, an inference unit configured to infer a body mark corresponding to the ultrasonic image data acquired by the acquisition unit, and a display control unit configured to display the body mark inferred by the inference unit together with the ultrasonic image data.

Information processing apparatus, information processing method, non-transitory computer readable storage medium, and ultrasonic diagnosis apparatus

An image processing device disclosed in the present specification includes a display control unit configured to display, on a display unit, an image obtained by visualizing functional information related to optical characteristics of a subject based on a photoacoustic signal obtained by receiving a photoacoustic wave generated in the subject by irradiating the subject with light, and a correction unit configured to correct the functional information of the image displayed on the display unit based on a first image value of the functional information of the image displayed on the display unit and a second image value of the functional information.

Image processing device, image processing method, and program

An information processing apparatus includes a first image acquisition unit configured to acquire first image data derived from a photoacoustic wave generated by light irradiation, a position acquisition unit configured to acquire position information indicating a position in the first image data having an image value that is within a predetermined range, a neighborhood position acquisition unit configured to acquire neighborhood position information indicating a neighborhood position neighboring the position based on the position information, and a display control unit configured to cause a display unit to display an image based on the first image data, the position information, and the neighborhood position information.

Information processing apparatus, information processing method, and non-transitory storage medium

An information processing apparatus uses signals obtained by a plurality of reception units that receive an acoustic wave propagating from a point of interest to acquire object information at the point of interest. The apparatus includes a speed-of-sound acquisition unit that acquires information representing speed of sound on a propagation path of the acoustic wave, a correction unit that acquires a correction amount for the information representing speed of sound and corrects the information representing speed of sound using the correction amount, and an information acquisition unit that determines a propagation time of the acoustic wave by linearly approximating propagation paths from the point of interest to the reception units based on the corrected information and acquires the object information at the point of interest based on the signals and the propagation time.
