  • Radiographic imaging apparatus
    Patent number: 11751835
    Abstract: A radiographic imaging apparatus (100) is configured to generate movement maps (30) of pixels (21) belonging to a first image (11) based on the first image (11) and a second image (12) captured at different times, to move a pixel (21) of the first image (11) based on a smoothed movement map (30a) in which high-frequency components of the movement maps (30) have been suppressed in a spatial direction and generate a deformed image (11a), and to combine the deformed image (11a) and the second image (12).
    Type: Grant
    Filed: April 19, 2018
    Date of Patent: September 12, 2023
    Assignee: Shimadzu Corporation
    Inventors: David Thibault Pelletier, Shota Sato, Shohei Okubo
  • Radiographic imaging apparatus
    Patent number: 11426139
    Abstract: A radiographic imaging apparatus includes an image generator configured to generate a plurality of first images and a plurality of second images, and an image processor configured to align common regions between the plurality of first images and generate a difference long image by splicing images obtained by subtracting a plurality of corrected images from the plurality of second images.
    Type: Grant

  • Radiation fluoroscopic imaging apparatus
    Patent number: 11179131
    Abstract: In this radiation fluoroscopic imaging apparatus, an image processing unit is configured to generate a first image by performing first image processing that clarifies a blood vessel as an imaging target when capturing a plurality of contrast agent images and generate a plurality of second images used to generate a differential long image by performing second image processing.
