Development of digital refraction-contrast tomosynthesis

折射对比度数字乳腺断层合成摄影系统是结合X射线暗场成像和数字断层合成摄影的X射线光学系统而开发的，旨在实现乳腺等软组织内部结构的断层图像可视化。我们成功地重建了乳腺组织的断层图像，这在吸收对比度图像中几乎没有图像对比度，以描绘乳腺肿块的内部结构和钙化分泌物的一些区域。

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.
