  • X-ray CT apparatus and image processing method
    Patent number: 9636076
    Abstract: An X-ray CT apparatus according to an embodiment includes an image processing circuit. The image processing circuit generates image data of an inside of a patient. The image processing circuit specifies a position of a tumor and a position of a surrounding site positioned in a surrounding of the tumor, from the generated pieces of image data. The image processing circuit calculates movement information related to movements of the tumor and the surrounding site, based on the specified positions of the tumor and the surrounding site. The image processing circuit calculates a relative relationship between the calculated movement information of the tumor and the surrounding site. The imaging processing circuit calculates a degree of coupling by which the tumor and the surrounding site are coupled, based on a relative relationship between the movement information of the tumor and the surrounding site.

  • X-ray CT apparatus and image processing method
    Patent number: 9230334
    Abstract: An X-ray CT apparatus according to an exemplary embodiment includes: a specifying unit that specifies the position of a lesion and the position of a surrounding site positioned in a surrounding of the lesion, from pieces of image data of the inside of the patient corresponding to the mutually-different temporal phases; a movement information calculating unit that calculates movement information related to movements of the lesion and the surrounding site, based on the positions of the lesion and the surrounding site specified by the specifying unit; and a relative relationship calculating unit that calculates a relative relationship between the movement information of the lesion and the movement information of the surrounding site calculated by the movement information calculating unit.
