Abstract
High-dose radiation destroys cancer cells in radiation therapy. Verification imaging is performed to adjust the patient's position to precisely target the tumor. We have applied a refraction contrast imaging technique to verification imaging to improve the accuracy of radiation treatment. The edge enhancement effect in refraction contrast imaging can produces higher contrast images than those in conventional imaging. In this study, rat skull images were obtained by refraction contrast imaging and conventional imaging for the evaluation of image quality improvement.
