Abstract
New approaches to the X-ray imaging of joints using different radiation sources are discussed. The structure of a joint cartilage tissue and model objects similar to the cartilage tissue in structure and properties have been studied using X-ray radiation of a laboratory microtomograph and synchrotron radiation. Projection radiography and microtomography images of the internal structure of the model objects and cartilage tissue impregnated with a radiopaque substance have been obtained. Colloidal solutions of titanium and molybdenum oxide bronze biofunctional nanoparticles have been used as contrast agents. The tissue depth distribution of the nanoparticle concentration has been measured by processing the images.
摘要 讨论了利用不同辐射源对关节进行 X 射线成像的新方法。利用实验室显微断层显像仪的 X 射线辐射和同步辐射研究了关节软骨组织的结构以及在结构和特性上与软骨组织相似的模型物体。获得了模型物体和浸渍了不透射线物质的软骨组织内部结构的投影射线照相术和显微断层照相术图像。钛和氧化钼青铜生物功能纳米粒子的胶体溶液被用作造影剂。通过处理图像，测量了纳米粒子浓度的组织深度分布。
期刊介绍：
Crystallography Reports is a journal that publishes original articles short communications, and reviews on various aspects of crystallography: diffraction and scattering of X-rays, electrons, and neutrons, determination of crystal structure of inorganic and organic substances, including proteins and other biological substances; UV-VIS and IR spectroscopy; growth, imperfect structure and physical properties of crystals; thin films, liquid crystals, nanomaterials, partially disordered systems, and the methods of studies.
