X-ray Tomography with Grating Interferometry (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 using grating-based X-ray phase tomography, which excels in contrast, albeit with some blurring when compared to propagation-based phase-contrast X-ray imaging (see image #1).
