| 20080267355 | X-Ray Sources - An anode for an X-ray source is formed in two parts, a main part and a collimating part. The main part has the target region formed on it. The two parts between them define an electron aperture through which electrons pass to reach the target region, and an X-ray aperture through which the X-rays produced at the target leave the anode. The anode produces at least the first stage of collimation of the X-ray beam produced. | 10-30-2008 |

| 20090316855 | Control Means for Heat Load in X-Ray Scanning Apparatus - The present invention is an X-ray scanning system having at least one multi-focus X-ray tubes spaced around an axis and arranged to emit X-rays through an object on the axis. The emitted X-rays are detected by sensors. Each multi-focus X-ray tube can emit X-rays from a plurality of source positions. In an exemplary scanning cycle, each of the source positions in each X-ray tube is used at least once and ordered to minimize the thermal load on the tubes. | 12-24-2009 |
| 20100172476 | X-Ray Tubes - An X-ray tube comprises an electron source in the form of a cathodE ( | 07-08-2010 |
| 20110007876 | Graphite Backscattered Electron Shield for Use in an X-Ray Tube - The present invention is a shielded anode having an anode with a surface facing an electron beam and a shield configured to encompass the anode surface. The shield has at least one aperture and an internal surface facing the anode surface. The shield internal surface and anode surface are separated by a gap in the range of 1 mm to 10 mm. The shield of the present invention is fabricated from a material, such as graphite, that is substantially transmissive to X-ray photons. | 01-13-2011 |
