| 20090039562 | Method for producing an anti-scatter grid or collimator made from absorbing material - A method is proposed for producing an anti-scatter grid or collimator for a radiation type, which is formed from at least one base body of prescribable geometry having transmission channels or slits for primary radiation of the radiation type which extend between two opposite surfaces of the base body. The base body is formed from a structural material that strongly absorbs the radiation type, either using the injection molding technique or by way of the technique of stereolithography. The method can be used to produce an anti-scatter grid or collimator with high accuracy and with the aid of only a few steps. | 02-12-2009 |
| 20100111247 | Computed tomography device with active adaptation of the measuring electronics - A computed tomography device (CT device) includes a user interface, via which the standard settings characterizing the CT measurement can be performed. At the same time, in a method and a computed tomography device for carrying out this method, filtering behavior of the filter electronics is adapted to the configuration of the standard settings by the system computer. | 05-06-2010 |

| 20100034345 | Radiation converter and method for producing the same, radiation detector and tomography device - A radiation converter is disclosed. In at least one embodiment, the converter is for x-ray or gamma radiation and includes a multiplicity of scintillation elements which are separated from one another by separating septa. To reduce cross-talk between adjacent scintillation elements, the separating septa have a layer structure. The layer structure includes two backscatter layers, between which an absorber layer which is essentially opaque to the radiation, to scatter radiation and/or scintillation light is disposed. | 02-11-2010 |
| 20100220834 | Method for Producing Projective and Tomographic Images Using an X-Ray System - An embodiment of the present invention discloses a method for producing projective and tomographic images using X-rays, allowing structures of similar composition to be imaged particularly well by combined evaluation of the behaviour of the test object with respect to the phase displacement during passage of the X-rays and its absorption. At least one embodiment of the invention also relates to an X-ray system and a CT system with respective source grids, phase grids, and analytical grids for carrying out the method. | 09-02-2010 |
| 20100232568 | X-RAY OR GAMMA RAY DETECTOR ARRAY - An X-ray or gamma ray detector array is disclosed, with at least one row of detector elements including at least one layer made of an X-ray or gamma radiation absorbing conversion material. In at least one embodiment, the conversion material is at least in part composed of a chemical element with an atomic number ≧72, preferably >82. Such an X-ray or gamma ray detector array allows an increased spatial and spectral resolution and better dose usage. | 09-16-2010 |

| 20090297140 | MEASURING CHROMATIC DISPERSION IN AN OPTICAL WAVELENGTH CHANNEL OF AN OPTICAL FIBER LINK - Two intensity modulated test signals are generated with precise frequency offset from a single laser source, and multiplexed into a combined test signal. The two modulated signals are demultiplexed at a receiver using a fixed periodic optical filter with complementary output ports. Group velocity dispersion/chromatic dispersion is measured over a large dynamic range, using pseudo-random intensity modulation and digital demodulation techniques. | 12-03-2009 |
| 20090316153 | DETERMINING IN-BAND OPTICAL SIGNAL-TO-NOISE RATIOS IN OPTICAL SIGNALS WITH TIME-VARYING POLARIZATION STATES USING POLARIZATION EXTINCTION - A method and apparatus for improving the accuracy of in-band OSNR measurements using a conventional polarization extinction or polarization-nulling method. In particular, the severe degradations of the polarization extinction that result from slow and fast polarization fluctuations in the optical signal components during the in-band OSNR measurement are substantially mitigated by rapidly and/or randomly changing the state of polarization prior to conventional polarization control and filtering. | 12-24-2009 |
