Nondestructive X-ray imaging of inner structure of soft tissues in phase contrast

An experimental study on nondestructive X-ray imaging of inner structure of soft tissues in phase contrast has been conducted with Beijing Synchrotron Radiation Facility (BSRF). Modification to the beamline setup was made to enlarge the X-ray beam section and consequently larger samples could be imaged. In-line setup was employed for experiments. Results on a series of samples were given and soft-tissue details of less than 50μm inside a fresh goldfish were obtained. Diagnosis of tumor in its early stage was also investigated taking SD rats as the model. Tumor at the size of -100μm was observed. Potential of this technique in clinic diagnosis was discussed.
