A radiography system (10) used for radiography includes two imaging units (11) including an imaging unit (11S) including a radiation source (12) and an imaging unit (11D) including a radiation detector (13), in which at least one imaging unit of the two imaging units (11) includes a projection apparatus (21) that projects a positioning indicator used for relative positioning between the two imaging units (11).

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 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.

Provided are a radiography system, an image processing device, an image processing method, and an image processing program that prevent an image of a correction marker from being included in a reconstructed region of a tomographic image obtained by reconstructing a plurality of projection images. A radiography system includes a correction marker that is used to obtain a marker image included in at least one of a plurality of projection images obtained by tomosynthesis imaging, is provided in an irradiation path of radiation in a radiation emitting unit, and is disposed at the position where the marker image is included in a region other than a reconstructed region in the projection image, the reconstructed region being a region used in a case in which the tomographic image is reconstructed from the plurality of projection images among the regions included in the plurality of projection images.

Provided are a control apparatus, an imaging system, a control method, and a control program which can improve visibility in a case in which information is projected onto a breast via a compression member. A console includes at least one processor (51), in which the processor detects a color of a projection region set in advance in at least a part of an upper surface (43A) of a transparent or translucent compression member (40) for putting a breast (H) into a compressed state, the upper surface being located on a side opposite to a contact surface (43B) of the compression member with the breast, acquires a projection image projected onto the projection region by a projector (39), and corrects a first pixel value of each pixel forming the projection image, based on the color of the projection region.

Provided are a white balance adjustment jig (10, 60, 80) for an endoscope and a white balance adjustment method for an endoscope that enable appropriate white balance adjustment for any of a plurality of types of endoscopes. A white balance adjustment jig for an endoscope includes: an insertion portion (11) that includes at least one insertion hole into which a distal end part (14a) of an endoscope is inserted; a lid portion (12, 62, 82) that is disposed to face the insertion portion (11); and an outer peripheral portion (13, 63) that is in contact with the insertion portion (11) and the lid portion (12, 62, 82) to form an internal space. The lid portion (12, 62, 82) includes a chart (18) having a plurality of marks on a surface on an insertion portion side, and the chart (18) is inclined with respect to a perpendicular plane perpendicular to the insertion direction of the distal end part.

Provided are an endoscope operation part and an endoscope capable of improving usability of an operation switch.An operation switch (56) that is housed in a housing recess (57) of a switch disposition surface located in an operation part main body (20) and between a bending operation knob (29) disposition surface and a universal cable (21) connection surface and that is configured to swing in a longitudinal axis direction is provided, and in a case where the endoscope operation part is viewed from a side facing the switch disposition surface, a position of a top portion of the operation switch in the longitudinal axis direction is located upward of a center position of a universal cable connection portion in a state in which the operation switch is not operated.
