Structural investigations of materials in diverse fields such as biomimetics, materials engineering, and medicine have much to benefit from 3D nondestructive microscopy of representative samples of wet tissues. Phase contrast appearing in tomograms produced by Fresnel propagation of partially coherent x-ray fields is useful for visualizing submicrometer features within water-immersed samples. However, spurious contributions such as those due to randomly appearing bubbles lead to distorted… CONTINUE READING
