20090024699 | INTEGRATION OF A MEDICAL WORKSTATION INTO A CLIENT-SERVER SYSTEM - In a method, a system and a computer program product for electronic data processing, communication and/or data retention in a computer-supported medical technology system to which multiple modules are connected that are involved in data exchange via a computer network, local workstations are thereby integrated or incorporated into a client-server system. A workstation thus embodies a client component and a workstation component. The client component serves for access to the central server. The workstation component serves for access to the local data of the workstation. Data exchange via the server with automatic synchronization occurs among all modules, in particular between the client component and the workstation component, such that consistent data sets are always stored and processed. | 01-22-2009 |
20090043841 | METHOD AND SYSTEM FOR PROVISION OF IMAGE DATA FROM A SERVER TO A CLIENT - In a method, a device and a computer program product for provision of image data such as thin slice image data and thick slice image data of a server to a client, the image data having been acquired by an imaging modality and being cached in a cache acting as a server; the image data are provided to the client by involving the client in data exchange with the server, and an information system that is likewise involved in data exchange with the server is always automatically informed about a current state of the cache, in particular about thin slice image data available in the cache. The client directly or indirectly accesses the image data of the cache for automatic provision of the image data. | 02-12-2009 |
20090077197 | METHOD, PRE-FETCH SERVER, AND SYSTEM FOR PRE-FETCHING THIN AND THICK SLICE IMAGE DATA - In a method and a system to provide medical image data sets stored in a data archive, wherein an image data set contains either thin slice data or thick slice data. A determination is made as to whether a requested image data set contains thin slice data or thick slice data by means of a detection feature associated with the image data set. The image data set is transmitted to a communication system if the image data set contains thick slice data; otherwise the image data set is transmitted to a buffer. The thick slice data are provided at a communication system and the thin slice data are provided to the buffer for a client. | 03-19-2009 |
20110019801 | METHOD FOR PRODUCING A 2D COLLIMATOR ELEMENT FOR A RADIATION DETECTOR AND 2D COLLIMATOR ELEMENT - A method is disclosed for producing a 2D collimator element for a radiation detector, in which crossing webs made of a radiation-absorbing material are formed, layer-by-layer, by way of a rapid manufacturing technique. In at least one embodiment, the webs are aligned along a φ- and a z-direction and form a cell-shaped structure with laterally enclosed radiation channels, at least in the inner region of the 2D collimator element. In at least one embodiment, the invention moreover relates to a 2D collimator element for a radiation detector that has such a layered construction. This allows the provision of a very precise and rigid collimator arrangement which, at the same time, has a high collimation effect. | 01-27-2011 |

20130251111 | METHOD FOR ENERGY CALIBRATING QUANTUM-COUNTING X-RAY DETECTORS IN A DUAL-SOURCE COMPUTED-TOMOGRAPHY SCANNER - A method is disclosed for energy calibrating quantum-counting x-ray detectors in an x-ray installation including at least two x-ray systems turnable around a center of rotation. A target, for producing x-ray fluorescence radiation, is positioned between the first x-ray source and first x-ray detector and irradiated with x-radiation of the first x-ray source in such a way that x-ray fluorescence radiation which strikes the second x-ray detector from the target is produced by the x-radiation of the first x-ray source. The second x-ray detector is then energy calibrated by way of the x-ray fluorescence radiation of the target. The first x-ray detector can be energy calibrated in the same way with the aid of the x-radiation of the second x-ray source. With the proposed method, the x-ray detectors of a dual-source CT x-ray installation can be calibrated with little expenditure under conditions close to those of the system. | 09-26-2013 |
20150069252 | X-RAY DETECTOR AND METHOD - An x-ray detector is disclosed for detection of x-ray radiation, including a planar cathode, an anode divided into a plurality of pixel elements and a direct converter disposed between cathode and anode for conversion of radiation into electrical charge. In an embodiment, at least two guard rings or guard ring structures are disposed around pixel elements or groups of pixel elements, to which guard rings or guard ring structures potentials are applied. Different potentials are applied to at least two different rings of the at least two guard rings or parts of the guard ring structures. | 03-12-2015 |
20150078534 | SCATTERED RADIATION GRID OF A CT DETECTOR - A scattered radiation grid of a CT detector is disclosed and includes a plurality of detector elements arranged in multiple cells in the phi direction and in the z direction of a CT system, having a plurality of free passage channels arranged to correspond to the detector elements, and walls fully enclosing the free passage channels at the longitudinal sides thereof. According to an embodiment of the invention, the walls of the scattered radiation grid are produced using a 3D screen-printing method. | 03-19-2015 |
