| Research Abstract |
High-dose radiation destroys cancer cells in radiation therapy. Verification imaging is performed to adjust the patient’s osition 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 ages than those in conventional imaging. In this study, laboratory-animal images were obtained by the refraction contrast imaging and conventional imaging for the aluation of image quality improvement.
