对光学方法的适用性进行了评估,如 胶原蛋白形态的非破坏性评价方法 在完整的生物瓣膜小叶中。结果表明, 传输偏振光和入射偏振光光学元件 便于瓣膜固有双折射的成像 胶原蛋白纤维,并用于确定胶原蛋白的模式 未植入和可移植材料的构型和取向 猪主动脉瓣膜和牛心包生物假体。
英文摘要
An assessment was made of the suitability of optical methods as means of nondestructively evaluating the morphology of collagen in intact leaflets of bioprosthetic valves. The results demonstrate that transmitted polarized light and incident polarized light optics facilitate the imaging of the inherent birefringence of valvular collagen fibers and serve to determine the patterns of collagen configuration and orientation in unimplanted and explanted porcine aortic valvular and bovine pericardial bioprostheses.
