摘要： A metal frame x-ray tube (1), includes a gettering system (90) which, when activated, provides a layer (147) of gettering material (98) on a grounded conductive portion (72, 74) of a metal frame or envelope (14). The envelope defines an evacuated chamber (12), which houses an anode (10) and a cathode (18). Moving the gettering material to larger diameter portions of the frame enables substantially larger amounts of gettering material to be provided than in a conventional gettering system, which is typically housed in the cathode assembly (26). Moreover, multiple independently controllable gettering wires (92, 94) facilitate reactivating the gettering material plural times both during the manufacturing process and in the field. This ability to rejuvenate vacuum pumping capability in an x-ray tube that is starting to arc in the field allows for extended x-ray tube life.
摘要翻译：金属框架X射线管（1）包括吸气系统（90），该吸气系统（90）当被激活时，在金属框架的接地导电部分（72,74）上提供吸气材料层（147）信封（14）。信封限定了一个真空室（12），其容纳阳极（10）和阴极（18）。将吸气材料移动到框架的较大直径部分使得能够提供比通常容纳在阴极组件（26）中的常规吸气系统中更大量的吸气材料。此外，多个可独立控制的吸气丝（92,94）有助于在制造过程中和在现场中多次重新吸收吸气材料。这种在现场开始弧形的x射线管中恢复真空泵送能力的能力可以延长X射线管寿命。

摘要： A rotation monitoring system (70) detects the rotational speed of an anode (10) of an x-ray tube during use. The system (70) includes a detector (72), which detects a pulse of secondary x-rays generated by the interaction of a stream (C) of electrons with a known defect (83) on a surface (84) of the anode. The detector may be position inside or outside a vacuum envelope (14) of the x-ray tube. The stream of electrons is supplied by a secondary source (80), separate from a main source (18) of electrons used to generate the primary or working x-ray beam (B) of the x-ray tube. A single pulse is detected with each rotation of the anode, providing a simple method of calculation of the anode rotation speed. Preferably, a feed back loop is used to correct the rotational speed of the anode so that overheating of the anode is avoided and the useful life of the x-ray tube is extended.
摘要翻译：旋转监视系统（70）在使用期间检测X射线管的阳极（10）的旋转速度。系统（70）包括检测器（72），其检测由阳极的表面（84）上的电子流（C）与已知缺陷（83）的相互作用产生的二次x射线的脉冲。检测器可以位于X射线管的真空外壳（14）的内部或外部。电子流由与用于产生X射线管的主要或工作X射线束（B）的电子的主源（18）分离的次级源（80）提供。通过阳极的每次旋转来检测单个脉冲，提供了计算阳极转速的简单方法。优选地，使用反馈回路来校正阳极的旋转速度，从而避免阳极的过热，并延长x射线管的使用寿命。

摘要： An x-ray system 20 includes an x-ray tube insert (24) that has an evacuated envelope (34), an anode assembly (38) and a cathode assembly (40). The anode assembly (38) and the cathode assembly (40) are located in operative relationship to one another within the evacuated envelope (34). A temperature indicating member (100) is located in thermally conductive contact with at least one assembly (38, 40, 66) located in the x-ray tube insert (24). The temperature indicating member (100) has a temperature sensitive characteristic which changes in response to adequate thermal exposure to at least one temperature threshold value.
