X-ray Tomography with Propagation-Based Imaging (image) American Institute of Physics Share Print E-Mail Caption Phase-contrast imaging is a technique for scanning the volumes of soft tissues like tumors or internal organs, but with much greater contrast than conventional CT scans. This image shows a non-invasive 'slice' of a rat's heart tissue made with X-ray phase tomography by propagation-based imaging, which provides sharper data with higher resolution than phase tomography using X-ray grating interferometry (see image #2).
