  • Patent number: 10973473
    Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an X-ray movable diaphragm and processing circuitry. The X-ray movable diaphragm limits an irradiation field of an X-ray. The processing circuitry sets an FOV size related to the irradiation field, sets a virtual field of view having the FOV size, the virtual field of view being able to include an outside region of an X-ray detection region and at least a part of the X-ray detection region, and controls the X-ray movable diaphragm so as to apply the X-ray to a common region between the virtual field of view and the X-ray detection region.

  • Patent number: 10342503
    Abstract: An X-ray image processing apparatus includes a storage unit, a transformed image generation unit, a scattered ray image generation unit, and a scattered ray reduced image generation unit. The storage unit stores a medical image. The transformed image generation unit generates a transformed image by transforming pixel values, of a plurality of pixel values constituting the medical image, which are higher than a reference value obtained based on a representative value of the plurality of pixel values into pixel values lower than the reference value. The scattered ray image generation unit generates a scattered ray image based on the transformed image and a scattering function. The scattered ray reduced image generation unit generates a scattered ray reduced image with reduced scattered rays by using the medical image and the scattered ray image.

  • Patent number: 9504294
    Abstract: A female snap is provided with: a first member for at least partially establishing an opening into which a post is inserted; and a second member which is able to restrict expansion of the opening in order to either increase the force needed for engagement/disengagement, or prohibit engagement/disengagement, of the post with respect to the female snap. The extent of expansion of the opening that is permitted by the second member varies depending on the relative positions of a contracting part of the second member and a contacted part of the first member in a peripheral direction going around the direction of insertion of the post into the opening.

  • Publication number: 20140193082
    Abstract: According to one embodiment, an image processing apparatus includes following units. The selection unit selects a pixel from a target image. The first extraction unit extracts a first pixel region including the selected pixel. The second extraction unit extracts a second pixel region from a reference image. The determination unit determines a filter coefficient based on a similarity degree between the first and second pixel regions. The generation unit generates a display image by performing a weighted sum of the target image and a display image generated immediately before the target image, in accordance with the filter coefficient determined for each of the plurality of pixels of the target image.
