血管无造影剂X射线定量相衬成像

Application of x-ray Phase Contrast Imaging to Angiography without Contrast Media

为克服血管造影术的缺点并提高分辨率,采用X射线定量相衬成像方法进行了血管成像研究.结果表明,采用该方法进行血管成像不存在造影剂对样品的危害,有效提高了成像分辨率,可获得微血管的精确尺度.

In order to eliminate the hazards of contrast agent and increase the resolution,X-ray quantitative phase contrast imaging has been applied to angiography without contrast media.The results demonstrated that through XQPCI could get the exact size of sample without contrast media.
