    摘要： The present invention provides a radiographic imaging device and a radiographic imaging method that suppress enlargement in size of image data after pixel density conversion while improving resolution. Namely, a radiographic imaging device includes a radiation detection element including plural same sized hexagonal shaped pixels that detect radiation and are arrayed in a honeycomb pattern, and a pixel density conversion section that performs interpolation processing such that first image data obtained from the radiation detection element is converted into second image data representing an image in which plural pixels are arrayed in a square grid pattern, wherein when d1max denotes the length of the longest diagonal of the hexagonal shaped pixels, S1 denotes the surface area of the hexagonal shaped pixels, and d2max denotes the length of the diagonals of the square grid of the second image data, d1 max is equal to or greater than d2max, and d2max is equal to or greater than the value of the square root of S1.

    摘要： Systems 10 and methods 200 of imaging an organ 0 of a patient include obtaining a plurality of two-dimensional (2D) tomosynthesis projection images of the organ 0. An x-ray image of the organ is obtained. A three-dimensional (3D) volume of the organ is reconstructed from the plurality of projection images and the x-ray image. A synthetic 2D image of the organ 0 is generated from the plurality of projection images and the x-ray image. The x-ray image is mapped to the 3D volume. A user selection of an object of interest in the x-ray image or the synthetic 2D image is received. A plane through the 3D volume that crosses the selected object of interest is identified and displayed.

    摘要： In a biopsy needle (100) according to the present invention, a moving mechanism is configured to cause each of an outer needle (110) and an inner needle (120) to independently slide in a longitudinal direction, and configured such that a maximum distance by which an outer needle (111) is slidable in a distal end direction is set to be longer than a maximum distance by which the inner needle (120) is slidable in the distal end direction such that, by movement of the moving mechanism, the outer needle (110) and the inner needle (120) switch between a first state, in which a second needle tip (121) of the inner needle is positioned closer to a distal end than a first needle tip (111) of the outer needle, and a second state, in which a position of the first needle tip (111) in the longitudinal direction is located closer to the distal end than a proximal end of an inclined surface (122) of the inner needle and a distance (D 2 ) between the first needle tip and the second needle tip is shorter than a distance (D 1 ) between the first needle tip and the second needle tip in the first state.
