A radiography system includes a radiation source unit (40) and a panel unit (60). The radiation source unit includes a radiation emitting unit (42) and a radiation source base part (50). The panel unit includes a panel (62) that detects radiation, and a panel base part (70). A floor surface is defined as a projection surface, and a projection region of the radiation source base part and a projection region of the panel base part have a common shape. The radiation source unit and the panel unit can be disposed in a close state where the floor surface is defined as a projection surface and at least one of a projection region of the radiation source unit and the projection region of the panel base part or a projection region of the panel unit and the projection region of the radiation source base part at least partially overlap with each other.

There are provided an ultrasound diagnostic apparatus and a control method of the ultrasound diagnostic apparatus by which a user can reliably perform comprehensive scanning of an organ.An ultrasound diagnostic apparatus includes an ultrasound probe (1); a position and posture sensor (13) that acquires position and posture information of the ultrasound probe; an image acquisition unit (32) that acquires an ultrasound image of a subject; a contour detection unit (25) that detects a contour of an organ imaged in the ultrasound image; a region detection unit (27) that detects a region of the organ imaged in the ultrasound image; a contour data generation unit (26) that generates three-dimensional image data of the contour on the basis of the detected contour and the position and posture information; a region data generation unit (28) that generates three-dimensional image data of the region on the basis of the detected region and the position and posture information; and a monitor (23) that sequentially displays an image representing the contour and an image representing the region on the basis of the three-dimensional image data of the contour and the region.

Provided are a control method of an ultrasound diagnostic apparatus and an ultrasound diagnostic apparatus capable of improving detection accuracy of a target inside a subject.An ultrasound diagnostic apparatus includes: an ultrasound probe (1); an image acquisition unit (31) that acquires an ultrasound image of a subject using the ultrasound probe and in accordance with a plurality of parameters related to image acquisition; a specific target detection unit (25) that detects a specific target from the ultrasound image using a machine learning model; and a preset setting unit (26) that sets and supplies different presets to the image acquisition unit during an operation and during a non-operation of the specific target detection unit for a predetermined preset among the plurality of parameters.

Provided are a control method of an ultrasound diagnostic apparatus and an ultrasound diagnostic apparatus capable of improving detection accuracy of a target inside a subject.An ultrasound diagnostic apparatus includes: an ultrasound probe (1); an image acquisition unit (31) that acquires an ultrasound image of a subject using the ultrasound probe and in accordance with a plurality of parameters related to image acquisition; a specific target detection unit (25) that detects a specific target from the ultrasound image using a machine learning model; and a parameter setting unit (26) that sets, for a parameter which is settable by a user among the plurality of parameters, different adjustment ranges of the parameter during an operation and during a non-operation of the specific target detection unit and that supplies the parameter, which is adjusted by the user, to the image acquisition unit.

Provided are a control method of an ultrasound diagnostic apparatus and an ultrasound diagnostic apparatus that enable a user to easily and accurately puncture a blood vessel of a subject. An ultrasound diagnostic apparatus includes: an ultrasound probe (1); an image acquisition unit (31) that continuously acquires an ultrasound image of a blood vessel using the ultrasound probe; a blood vessel detection unit (24) that detects the blood vessel from the ultrasound image; a blood vessel information acquisition unit (25) that acquires blood vessel information of the blood vessel detected by the blood vessel detection unit; a needle information acquisition unit (26) that acquires needle information of a puncture needle; an estimated reaching position calculation unit (27) that calculates an estimated reaching position of the puncture needle based on a designated insertion position of the puncture needle, the blood vessel information, the needle information, and a predetermined needle insertion angle range; a monitor (23); and a display controller (22) that displays the estimated reaching position calculated by the estimated reaching position calculation unit on the monitor.

Provided are an image processing device, an image processing method, and an image processing program that can easily determine a distribution of a faint calcification having low visible in a radiographic image.An image processing device includes at least one processor. The processor detects a faint calcification from a radiographic image captured by irradiating a breast with radiation and displays a calcification distribution image showing a distribution of the faint calcification in the breast in the radiographic image.
