Method for displaying medical images and medical image display system

摘要

The present invention provides a method for displaying medical images and a medical image display system that do not require a medical practitioner to move his/her line of sight at the time of comparing/interpreting images and that can improve accuracy in diagnosis. According to the medical image display system of the present invention: an X-ray imaging device captures an image of a subject according to a first imaging mode by a fringe-scanning imaging device or a second imaging mode by a Fourier transform imaging device; a controller creates at least two images from among an X-ray absorption image, a differential phase image, and a small-angle scattering image on the basis of the captured moir image; and said at least two images that have been created are displayed in turn in the same position on a display section.

主权项

1. A medical image display method comprising:
an imaging step of imaging a subject by a fringe scanning-type imaging apparatus or a Fourier transform-type imaging apparatus, the apparatus including an X-ray source that irradiates an X-ray, a first grating and a second grating, each of which being arrayed in a direction perpendicular to an irradiation axis direction of the X-ray, a subject platform, and an X-ray detector in which conversion elements generating electric signals in response to the irradiated X-ray are arranged two-dimensionally, the X-ray detector reading, as image signals, the electric signals generated by the conversion elements; an image processing step of creating an X-ray absorption image, a differential phase image and a small-angle scattering image by an image processing unit based on the image signals of the subject, the imaging signals being obtained in the imaging step; a first displaying step of displaying the X-ray absorption image created in the image processing step; a second displaying step of displaying at least one of the differential phase image and the small-angle scattering image created in the image processing step on the same position of a display unit while sequentially switching the X-ray absorption image and the at least one of the images; and a third displaying step of displaying the other one of the differential phase image and the small-angle scattering image created in the image processing step on the same position of the display unit while sequentially switching the at least one of the images and the other one of the images.
