画像誘導放射線治療のための放射光屈折コントラストイメージング  [in Japanese] Refraction Contrast Imaging Using Synchrotron Radiation for Image-Guided Radiation Therapy  [in Japanese]

High-dose radiation destroys cancer cells in radiation therapy. Verification imaging is done to adjust the patient's position to precisely target a tumor. To improve the accuracy of radiation targeting, we have applied a refraction contrast imaging technique to verification imaging. The edge enhancement effect in refraction contrast imaging can produces higher contrast images than those in conventional imaging. We obtained images of a rat skull by both refraction contrast and conventional imaging to evaluate improvements in image quality.
