20130119258 | METHOD AND APPARATUS FOR THE DETECTION OF X-RAY QUANTS - A method for the detection of X-ray quants is provided. The X-ray quants are generated in an X-ray tube and impact on a multi-pixel X-ray detector including a two-dimensional matrix of test-signal-generating pixels. The method includes assigning, by an evaluation unit, pixels that generate a test signal within a predetermined time interval and are located in a cohesive cluster including a plurality of pixels to an event cluster. The test signals are used to approximate a position, at which the X-ray quant has interacted with the multi-pixel X-ray detector. | 05-16-2013 |
20130287179 | Adaptive X-Ray Filter and Method for Adaptive Attenuation of X-Ray Radiation - An adaptive x-ray filter and an associated method for changing a local intensity of x-ray radiation are provided. The adaptive x-ray filter includes a first fluid absorbing x-ray radiation and hydraulically moveable positioning elements that change the layer thickness of the first fluid at a location of the respective positioning element by being able to at least partly displace the first fluid. | 10-31-2013 |
20130301807 | Adaptive X-Ray Filter - An adaptive X-ray filter for varying a local intensity of X-ray radiation includes a first chamber containing a magnetorheological or electrorheological first liquid, a second chamber containing a second liquid that absorbs X-ray radiation, and a flexible membrane that separates the first chamber from the second chamber. Using the flexible membrane, a layer thickness ratio of the first liquid and the second liquid may be varied. A heating apparatus that heats the second liquid is arranged in the adaptive X-ray filter. The second liquid is a liquid metal. | 11-14-2013 |
20130322604 | Adaptive X-Ray Filter for Changing the Local Intensity of X-Rays - An adaptive x-ray filter for changing a local intensity of x-rays includes an x-ray absorbing first fluid and electrically deformable control elements. The electrically deformable control elements change a layer thickness of the first fluid at a site of a respective electrically deformable control element by at least partially displacing the x-ray absorbing first fluid. | 12-05-2013 |
20130343516 | METHOD AND APPARATUS FOR FILTERING RADIO-FREQUENCY ELECTROMAGNETIC BEAMS AND IRRADIATION APPARATUS OR DEVICE FOR IRRADIATING AN OBJECT - A method and an apparatus for filtering radio-frequency electromagnetic beams, in particular x-rays, include a fluid container containing a ferrofluid which at least partially absorbs the electromagnetic beams. A distribution of the ferrofluid within the fluid container can be varied by using an applied magnetic gradient field. An irradiation apparatus and a device for irradiating an object are also provided. | 12-26-2013 |
