摘要： X-ray detector apparatus is provided for use in a CT imaging system having a rotatable gantry. The apparatus comprises a selected number of X-ray detector cells and two curved rails, which hold the detector cells in an array comprising an arcuate configuration and mount them onto the gantry for rotation therewith. Conduit segments are distributed along the rails, each conduit segment being proximate to a corresponding group of X-ray detector cells, and a quantity of selected working fluid and a porous wick structure is sealably enclosed in each conduit segment. The fluid is disposed to move along a conduit segment in gaseous form by means of convection, and to move in the opposing direction through the wick structure, in liquid form, by means of capillary action Heat is thereby transferred along a conduit segment to maintain a substantially isothermal condition among the detector cells proximate thereto.

摘要： A method of balancing X-ray anodes wherein the anode rotor is dynamically balanced separately from the anode target, the anode target is then attached to the anode rotor to provide the assembled anode, and the assembled anode is then dynamically balanced. This sequential balancing method has the advantage that it results in an anode which remains balanced during operation at speeds up to and exceeding the anode's critical speeds, even though the dynamic balancing steps may be performed at speeds substantially below the anode's critical speeds. This is also convenient because at such low balancing speeds, the dynamic balancing steps can be performed in air rather than vacuum without concern for oxidation and spalling of the rotor bearings, excessive vibration, and potential safety concerns.
摘要翻译：一种平衡X射线阳极的方法，其中阳极转子与阳极靶分开动态平衡，然后将阳极靶连接到阳极转子以提供组装的阳极，然后组装的阳极被动态平衡。这种顺序平衡方法具有的优点是，即使动态平衡步骤可以以低于阳极的临界速度的速度执行，其导致阳极在运行期间在高于和超过阳极的临界速度的速度下保持平衡。这也很方便，因为在这样低的平衡速度下，动态平衡步骤可以在空气而不是真空中进行，而不用担心转子轴承的氧化和剥落，过度的振动和潜在的安全性问题。

摘要： The saddle of a fluid flow detector is held in sealing relation to a conduit through an adapter. The adapter has an aperture that mates with an aperture in the conduit through which the actuator of the detector extends. The adapter is fabricated of a suitable plastic. In another embodiment, a bracket holds the saddle in a sealing relation to the conduit.

摘要： In a radiographic apparatus having an x-ray tube, a method is provided for continuously conditioning the dielectric fluid in the x-ray tube during operation, thereby extending the service life of the x-ray tube. This is achieved by mounting a filter inside a filter housing, and mounting a replaceable gas reduction cartridge around the filter. The replaceable gas cartridge is filled with a material having a high affinity for the dielectric fluid. When the dielectric fluid enters at the filter outside diameter, the fluid moves radially inward so that the dielectric fluid flows over the high affinity material surfaces. The dielectric fluid then alloys with the high affinity material, thereby continuously conditioning the fluid.
