摘要:
A system for creating a semantic data warehouse including a convergence service configured to execute queries to connected data sources, to convert data from source to domain semantics, and to aggregate converted data. The convergence service is configured to invoke by an entity graph service that, on demand, defines a semantic entity representation, the needed queries and data sources to be queried; and projects and makes available the resulting data in the semantic entity representation.

A radiation image capturing system includes a processing unit that determines at least three distances between at least one first distance sensor provided at a radiation generation unit and at least three second distance sensors provided at a detection unit based on one or more signals emitted by the first distance sensor, and that determines an orientation of the radiation generation unit and the detection unit relative to each other based on inclination information provided by a first sensor unit provided at the radiation generation unit and a second sensor unit provided at the detection unit. Alternatively, the processing unit determines distances between at least three first distance sensors provided at the radiation generation unit and at least three second distance sensors provided at the detection unit based on signals emitted by the at least three first distance sensors to determine an orientation of the radiation generation unit and the detection unit relative to each other.
摘要:
A method for performing a job list of radiographic recordings indicated in a radiographic information systems includes communicating the job list to a mobile apparatus, e.g. a smartphone, whereby, in a first step, a peer-to-peer communication is set up between the radiographic information system and the mobile apparatus by a Near Field Communication technique, whereupon the job list is transmitted to the mobile apparatus via a WIFI peer-to-peer communication. A radiographer then completes the job list by using, inter alia, a self-triggering direct radiographic panel and a radiographic generator.

A radiographic flat panel detector includes a layer configuration in the order given: a) a radiation transparent substrate; and b) a scintillator layer applied by vapor deposition on the radiation transparent substrate; and c) an imaging array between the scintillator layer and a second substrate, characterized in that the radiation transparent substrate has on a side a layer including magnetisable particles and a method for producing the radiographic flat panel detector.
摘要:
Volume data representing a radiation image of an object are subjected to a coarse filtering process to obtain a first classification including support type and non-support type components. An iteration of low threshold filtering steps and successive extraction and classification of connected components is performed and used to rectify the result of the coarse filtering process. A further filtering is based on the location of the connected components in the volume.

A method controls for a planned radiographic exposure the spatial position of a portable digital direct x-ray detector in a medical imaging system including multiple radiographic exposure stands. The method includes creating a three-dimensional spatial model of the medical imaging system, determining within the model the spatial position of the detector based on input received from three gravity sensors installed thereon, determining a three-dimensional volume space for each radiographic exposure stand, and checking whether the spatial position of the detector fits within the three-dimensional volume space of the radiographic exposure stand.
摘要:
A statistical analysis is performed on pixel values of at least one region of interest in an image obtained by substantially uniform irradiation of an x-ray detector and deciding upon the presence of a source of x-ray beam in-homogeneity by comparing the results of the statistical analysis with at least one predetermined acceptance criterion.
摘要:
A method for workflow management in a medical workflow management system wherein a first user logs in to the workflow management system running a desktop application and next identifies an additional, non logged-in user and defines at least one task of the workflow for this additional user. Selection of an additional user and defined task(s) triggers the workflow management system to associate the defined task(s) of the workflow with the additional user.
摘要:
A method for the determination of the delay time of a radiographic generator and to the setting of a standard value for such delay time. According to the method it is determined by a series of decreasing chosen values for the delay time whether a signal for the confirmation of the start of the radiographic exposure is rendered by the radiographic generator. The last value of the chosen delay time whereby still such a confirmation signal is rendered, is retained as standard operational value for the delay time of the radiographic system.
