Prototype represents a step toward enhanced soft-tissue tomography

A promising approach for producing medical images with enhanced soft tissue visibility -- grating-based x-ray phase contrast -- has now advanced from bench-top studies to implementation in an in vivo preclinical computed tomography scanner. This work could mark a critical step in moving beyond proof-of-concept experiments to applications -- including in vivo preclinical imaging with small-animal models in the mid-term future and, in the long term, medical CT scanning.
