phase contrast tomography

Phase contrast tomography is an imaging technique that uses X-ray waves to create detailed 3D images of objects, especially those with subtle differences in internal structure. Instead of solely relying on how much the material absorbs X-rays, it detects how the waves change phase as they pass through different parts of the sample. These phase shifts reveal fine details and variations in density or composition that are difficult to see with traditional X-ray imaging. This method is particularly useful for visualizing soft tissues, biological samples, or delicate materials with high precision and minimal damage.
