We report on a two-directional approach for grating based x-ray differential phase contrast imaging. In order to retrieve good quality and artifact-free phase images for quantitative analysis and image processing, particular emphasis is put on the algorithm for proper phase retrieval. Examples of application are discussed that demonstrate the functionality of the method even in cases where the one-dimensional phase integration fails completely.

  19. In fact, the quantity measured is not the absolute displacement ‹Δ›real ∝ ∂Φ/ ∂ x but ‹Δ›x = (‹Δx›real mod p2) because a steep phase gradient can shift the fringes more than one period p2. This phenomenon is known as phase-wrapping.
