  • X-ray CT apparatus, medical image processing apparatus, and X-ray CT system
    Patent number: 11295487
    Abstract: An X-ray CT apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires a first data set corresponding to first X-ray energy and a second data set corresponding to second X-ray energy different from the first X-ray energy, with respect to a region including a part of a subject by performing scanning using X-rays. The processing circuitry generates a scatter diagram representing a contained amount of each of reference materials at each of positions in the region on the basis of the first data set and the second data set. The processing circuitry sets weights for at least a part of the scatter diagram. The processing circuitry generates an analysis image based on the contained amounts and the weights.
    Type: Grant
    Filed: September 6, 2019
    Date of Patent: April 5, 2022
    Assignees: CANON MEDICAL SYSTEMS CORPORATION, National Cancer Center
    Inventors: Kotaro Sekiya, Hirofumi Kuno, Takashi Hiyama, Tsubomi Hashizume, So Tsushima, Shinsuke Tsukagoshi
  • X-ray CT apparatus including processing circuitry to perform a metal-artifact reducing process
    Patent number: 10610185
    Abstract: An X-ray CT apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to detect X-rays that have passed through a subject by using a detector and to acquire projection data on a basis of a detection result. The processing circuitry is configured to obtain position information of a highly X-ray absorbent member in the body of the subject. The processing circuitry is configured to derive information about transmission paths of the X-rays in accordance with a processing effect of an artifact reducing process performed on the highly X-ray absorbent member, on the basis of the position information of the highly X-ray absorbent member.
