X-ray imaging apparatus and method of X-ray imaging |
摘要 |
Provided is an X-ray imaging apparatus and a method of X-ray imaging, with which the apparatus can be reduced in size and a with which differential phase image or a phase image with consideration of an X-ray absorption effect of an object can be obtained. A displacement of X-rays that have been split by a splitting element and have passed through an object is measured. The displacement can be measured by using a first attenuation element having a transmission amount that continuously changes in accordance with the incident position of X-rays. At this time, an X-ray transmittance of an object that is calculated by using a second attenuation element having a transmission amount that does not change in accordance with the incident position of X-rays is used. |
