Raw data files of anatomical parameters in four porcine biomembranes

4 porcine biomembranes were investigatedPL = plica venae cavaeCT = centrum tendineumPE = pericardSIS = small intestinal submucosa
in terms of:1. Membrane thickness (native state of the membrane)2. D-periodicity, a collagen-specific feature (using scanning electron microscopy on fixed membranes)3. Fibril diameter of collagen fibers (using Scanning electron microscopy) 4. Volumetric Index (using multiphoton microscopy on native membranes) indicating volumes (v) of the collagen and elastin: VElastin-VCollagen/VElastin+VCollagenThis calculation yielded indexes from +1 (100% elastin) to -1 (100% collagen).
