Abstract:
A new X-ray phase contrast imaging method utilizing scanning absorption grid technology is proposed based on the study of X-ray phase contrast imaging with pinhole imaging principle.The method can effectively capture absorption,refraction,and scattering information of weakly absorbing biological samples.Experimental results show that the proposed method offers several advantages over traditional X-ray grating phase contrast imaging,including a simple imaging device,minimal X-ray source requirements,and enhanced compatibility with laboratory X-ray source or synchrotron radiation white beam.Consequently,it provides a new research mean for advancing current X-ray phase contrast imaging technology in clinical imaging research of large human organs.
