X-Ray Phase-Contrast

Early detection of cancer and angiography applications are just two examples that can directly benefit from an imaging modality with excellent soft-tissue contrast. X-ray grating interferometry is promising to achieve this while keeping radiation dose and examination costs low. Existing clinical X-ray systems can be retrofitted with a set of three gratings to form an interferometer. The measurement procedure yields three images: X-ray absorption, differential phase, and dark-field. The vision of phase-contrast X-ray is that these three complementary signals together enable highly sensitive tissue contrast for medical diagnosis and interventional applications.
