摘要： The present invention relates to applying an existing carbon nanotube X-ray tube for a dental X-ray imaging system that can replace a carbon nanotube electron emission source installed in a cathode portion. An X-ray tube system formed in a pen according to the present invention can be inserted in the oral cavity due to its thin thickness, thereby displaying an accurate image of an inner location of the oral cavity needing a diagnosis. For therapy of oral cancer requiring an appropriate amount of radiation therapy, since radiation can be directly irradiated to a diseased part, brachytherapy is enabled without concern of exposure dose of normal tissues. Therefore, when the system is commercialized, a great amount of distribution effect may be expected. The X-ray tube system that can be used for medical services such as a dental service includes an X-ray emission module emitting X-rays using a chipped nano-structured material, for example, carbon nanotube. The X-ray emission module is separable from a body in order to replace a cathode portion that is included in the X-ray emission module and is based on the nano-structured material.
摘要翻译：本发明涉及应用现有的用于牙科X射线成像系统的碳纳米管X射线管，其可以替代安装在阴极部分中的碳纳米管电子发射源。根据本发明的用笔形成的X射线管系统由于其厚度薄而能够插入口腔，从而显示需要诊断的口腔内部位置的精确图像。对于需要适量辐射治疗的口腔癌的治疗，由于辐射可以直接照射到患病部位，所以可以进行近距离放射治疗而不考虑正常组织的暴露剂量。因此，当系统商业化时，可以预期大量的分配效应。可用于医疗服务如牙科服务的X射线管系统包括使用切片纳米结构材料（例如碳纳米管）发射X射线的X射线发射模块。为了更换X射线发射模块中包含的阴极部分并且基于纳米结构材料，X射线发射模块可与主体分离。

摘要： A miniaturized, increased efficiency x-ray source for materials analysis includes a laser source, an optical delivery structure, a laser-driven thermionic cathode (108), an anode (122), and a target from the laser source and directs the beam onto a surface of the themionic cathode. The surfaces electrons form an electron beam along a beam path. The target element (110) is disposed in the beam path, and emits x-rays in response to incident accelerated electrons from the thermionic cathode. The target element includes an inclined surface that forms an angle of inclination (113) of about 40 degrees with respect to the electon beam path, so that x-rays are emitted from the target substantially at an angle of about 45 degrees with respect to the electron beam path.

摘要： In a miniature x-ray tube, which may be on the order of approximately 1 mm in diameter or even less, a high voltage cable is provided in various embodiments for conducting current to the cathode of the x-ray tube and for conducting high voltage to the cathode and anode of the tube. In various embodiments of the cable, two conductors occupy a center region of the cable, packed as closely together as possible, in various shapes that are compact and present as smooth as possible an external shape for maximizing dielectric properties against the exterior high voltage ground, surrounding and generally concentric with the inner conductors. The inner conductors, which carry high voltage in opposition to the outer ground, can be in opposed D shapes, coaxial, two flattened conductors side by side, or simply a pair of cylindrical wires positioned as closely as possible. The space between the inner conductors and the outer ground can be occupied by a glass insulator, polymer, successive layers of polymers and adhesive, air, gas, vacuum or other dielectrics. A partially conductive region can surround the inner conductors.
