Improved visualization of X-ray phase contrast volumetric data through artifact-free integrated differential images

Artifacts arising when differential phase images are integrated is a common problem to several X-ray phase-based experimental techniques. The combination of noise and insufficient sampling the high-frequency signal leads formation streak artifacts in projections, translating into poor image quality tomography slices. In this work, we apply non-iterative integration algorithm proven reduce planar (2D) scan. We report on how reduction projections improves slices, especially directions different from reconstruction plane. Importantly, method compatible with large datasets terms computation time.
