摘要
An experimental study on nondestructive X-ray imaging of inner structure of soft tissues in phase con-trast has been conducted with Beijing Synchrotron Radiation Facility (BSRF). Modification to the beamline setupwas made to enlarge the X-ray beam section and consequently larger samples could be imaged. In-line setup was em-ployed for experiments. Results on a series of samples were given and soft-tissue details of less than 50 μm inside afresh 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.

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.
