| Abstract: | X-ray fluorescence computed tomography is a stimulated emission tomography that allows nondestructive reconstruction of the elements distribution in the sample,which is important for biomedical investigations.Owing to the high flux density and easy energy tunability of highly collimated synchrotron X-rays,it is possible to apply X-ray fluorescence CT to biomedical samples.Reported in the present paper,an X-ray fluorescence CT system was established at Shanghai Synchrotron Radiation Facility for the investig... |
