摘要： An X-ray apparatus for image acquisition and a related method. The apparatus comprises a field-of-view corrector (CS) configured to receive a scout image (SI) acquired by the imager with a tentative collimator setting in a pre-shot imaging phase where said imager operates with a low dosage radiation cone causing the detector to register the scout image. The low dosage cone has, in the detector's image plane, a first cross section smaller than the total area of the detector surface. The field-of-view corrector (CS) uses said scout image to establish field-of-view correction information for a subsequent imaging phase where the imager is to operate with a high dosage radiation cone, the high dosage higher than the low dosage.

摘要： The present invention provides a phantom (200) for use in a magnetic resonance (MR) imaging system (110) with a set of resonating volumes (206) positioned in a base body (202), whereby the base body (202) has a spherical or ellipsoid shape in accordance with a volume of interest (203) of the MR imaging system (110), and the resonating volumes (206) are located at a circumference of the base body (202). The phantom is used in a method for evaluating the magnetic field of a main magnet (114) of a magnetic resonance (MR) imaging system (110), comprising the steps of positioning the phantom (200) within the main magnet (114), performing a 3D spectroscopic MR measurement of the phantom (200) using the MR imaging system (110), thereby measuring resonances of the resonating volumes (206), assigning the measured resonances to the resonating volumes (206), and evaluating the magnetic field of the main magnet (114) from the MR measurement of the phantom (200) based on the measured resonances of the resonating volumes (206). Accordingly, the MR imaging system itself is directly used for determining the magnetic field of its main magnet. Accordingly, the MR imaging system itself can be used as measurement equipment, instead of a separate NMR magnetometer, which is required for conventional determination of the magnetic field.

摘要： The present invention relates to transducer housing and a tool for opening and closing the transducer housing (20). The transducer housing comprises a base body (22) and a lid (24) which are releasable coupled with a rotational coupling (26). The lid (24) comprises a contact area (42) formed to be engaged by a driving pin (64) of the tool (10) in order to open or close the transducer housing (20) upon a rotation of the lid (24) relative to the base body (22). The tool (10) comprises a base portion (12) and an upper portion (14) that are coupleable wherein the upper portion can be rotated relative to the base portion. When coupled the upper portion and base portion may enclose the transducer housing such that upon a rotational movement of the upper portion (14) relative to the base portion (12) the driving pin (64) of the upper portion (14) engages with the contact area (42) of the lid (24) causing the lid (24) of the transducer housing (20) to move relative to the base body (22) of the transducer housing (20) resulting in an opening or closing of the transducer housing.

摘要： The invention relates to a method and an X-ray detector (100) for detecting incident X-ray photons (X). The X-ray detector (100) comprises at least one sensor unit (105) in which X-ray photons (X) are converted into sensor signals (s) and at least one flux sensor (104) for generating a flux signal (f) related to the flux of photons (X). The sensor signals (s) are corrected based on the flux signal (f). In a preferred embodiment, the sensor signals (s) represent a spectrally resolved pulse counting. The flux sensor (104) may be integrated into an ASIC (103) that is coupled to the sensor unit (105).

The energy dump unit disperses the energy outside of the cryostat.

摘要： The invention relates to an electrical device comprising an electrical unit (2) like an organic light emitting diode, a protection element (3) like a thin film encapsulation, which at least partly covers the electrical unit, for protecting the electrical unit against water and/or oxygen, and a detection layer (4) arranged between the protection element and the electrical unit or within the protection element, wherein the detection layer comprises organic material and is adapted such that a property of the detection layer is changed, if the detection layer is in contact with a contact gas usable for detecting a permeability of the protection element. This allows easily integrating a fast detection test for detecting a permeability of the protection element into a production process for producing the electrical device, i.e. a time consuming external permeability test may not be required.
