Method, apparatus and program for radiation imaging |
摘要 |
To provide a radiation imaging method using a phase contrast method capable of imaging efficiently with high estimation accuracy of restoring phase. The radiation imaging method includes, the steps of: (a) sequentially detecting intensity of radiation transmitted through an object at plural distances from the object in first order by using radiation having a first wavelength to obtain a first group of image signals; (b) sequentially detecting intensity of radiation transmitted through the object at plural distances from the object in the reverse order by using radiation having a second wavelength to obtain a second group of image signals; (c) restoring phase information of the radiation based on the first and second groups of image signals to obtain plural pieces of phase data; and (d) generating image data based on the plural pieces of phase data.
