In edge-illumination x-ray tomography, which yields phase contrast in addition to attenuation contrast, spatial resolution is decoupled from the size of the x-ray source's focal spot, and of the detector pixels, as the primary x-ray beam is structured in an array of narrow beamlets. This study provides a theoretical framework to explain how beamlet width sets spatial resolution in a tomographic phase-contrast image, and examines the effect of sampling during tomographic scans. The results will inform the design of advanced experimental setups and acquisition schemes, and help us understand how resolution is affected by constraints on scan time or dose.
