X-ray System for Early Diagnosis of Breast Cancer.

Increasing rate of breast cancer in Japan is enormous in these years. Nevertheless only 2–3 % of female may receive mammography. In order to improve this number for early detection of breast cancer we have started development of a refraction-based visualization of breast cancer. This system comprises two types of imaging: one is for a regular annual or biyearly check of the breast cancer. This is a 2-D mode x-ray dark-field imaging where a Laue transmission type of angle analyzer with thickness of 2.124 mm is used for the FOV of 90 mm × 90 mm that can provide the spatial resolution better than 50 microns; the other a 3-D reconstruction for further detailed check to specify type and location of breast cancer. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]
