An image processing apparatus comprises an obtaining unit that obtains a plurality of images obtained by irradiating radiation having different energies, a generating unit that generates a processed image by compositing the plurality of images, and a compositing unit that generates a composite image by compositing one image among the plurality of images and the processed image so as to enhance a low-frequency component of the one image and enhance a high-frequency component of the processed image.

Image processing apparatus and control method for same

The present invention provides an image display method that enables intuitive identification of a portion where a mammary gland region and a microcalcified region overlap each other in a radiographic captured image of a breast. The radiographic image data display method according to an aspect of the present invention includes detecting microcalcified regions and a mammary gland region in the radiographic image data, and displaying the microcalcified regions and the mammary gland region on a single screen.

Image processing apparatus and radiographic image data display method

A breast imaging device for rotating a radiation detection unit configured to detect radiation irradiated from a radiation generation unit configured to generate the radiation with the radiation detection unit and the radiation generation unit facing each other includes a ray sum image generation unit configured to generate a ray sum image based on an addition value of at least one pixel value in a visual line direction from volume data reconstructed from a projection image output from the radiation detection unit, a maximum intensity projection image generation unit configured to generate a maximum intensity projection image based on the maximum pixel value in the visual line direction from the volume data, and a synthesizing unit configured to synthesize the ray sum image and the maximum intensity projection image.

Breast imaging device, image processing device, and image processing method

There is provided a radiographic imaging apparatus capable of facilitating a comparative radiological interpretation of symmetric portions or a temporal comparative radiological interpretation of a same imaging target. The radiographic imaging apparatus includes an image control unit configured to cause a display unit configured to display a plurality of divided screens to display a first radiographic image of a first imaging target on a first divided screen of the plurality of divided screens. The image control unit causes a radiographic image of the first imaging target that is captured at a different time from the first radiographic image or a radiographic image of a second imaging target that is a symmetric imaging target of the first imaging target to be displayed on a second divided screen of the plurality of divided screens as a second radiographic image.

Radiographic imaging apparatus, radiographic imaging system, radiographic imaging method, and storage medium

A radiation CT apparatus includes a rotation unit configured to rotate about a rotation axis, a radiation generation unit and a radiation detector which are fixed on either side of the rotation axis in the rotation unit, and a gantry cover containing the radiation generation unit and the radiation detector and including a breast insert portion configured to insert a breast of an object. An opening portion that can be opened and closed is placed on the gantry cover of the radiation CT apparatus. The radiation generation unit and the radiation detector are stopped to form a space that allows a user to access the breast insert portion from the opening portion.

Radiation CT apparatus and method of controlling the same

A breast imaging apparatus includes a gantry which includes a radiation generation unit configured to generate radiation and a radiation detection unit configured to detect radiation generated by the radiation generation unit, the radiation generation unit and the radiation detection unit being capable of rotating facing each other, wherein the gantry is provided with a front cover configured to protect a subject from the radiation generation unit and the radiation detection unit which rotate during CT imaging, and the front cover has an opening in which the breast of the subject is inserted, and a breast holding portion configured to hold the breast of the subject inserted in the opening.

Breast imaging apparatus

An image processing apparatus obtains a three-dimensional radiation image of a right region of substantially symmetrical regions, obtains a three-dimensional radiation image of a left region of the substantially symmetrical regions, performs alignment between the three-dimensional radiation image of the right region and the three-dimensional radiation image of the left region based on a feature position of the regions, and substantially symmetrically arranges and displays the three-dimensional radiation image of the right region and the three-dimensional radiation image of the left region which have been aligned.

Image processing apparatus, image processing method, radiation imaging system, and non-transitory computer-readable storage medium

A movable X-ray generation apparatus includes an X-ray tube configured to perform irradiation with X-rays, an arm configured to support the X-ray tube, a cart unit configured to support and move the arm, and a monitor mounted on the upper portion of the cart unit. The movable X-ray generation apparatus includes a first member configured to support the monitor to be pivotable about a first rotation axis, and a second member configured to support the first member to be pivotable about a second rotation axis different from the first rotation axis with respect to the cart unit. At least one of the first rotation axis and the second rotation axis provides a rotation axis parallel to the display surface of the monitor and perpendicular to a moving surface on which the cart unit moves.
