Development of digital refraction-contrast tomosynthesis

Refraction-contrast digital breast tomosynthesis system was developed in combination with X-ray optics for X-ray dark-field imaging and digital tomosynthesis, by which we aim at visualizing internal structures of soft tissues such as breast in slice images. We successfully reconstructed tomograms of breast tissues, which have little image contrast in absorption contrast images, to depict internal structures of breast mass and some of regions with calcific secretion.
