Abstract: An imaging method for radiologically guiding an instrument during medical interventions on an object comprising: providing a first image of said object followed by providing updated images on-the-fly during the intervention to an operator by measuring an undersampled set of projections of said object and reconstructing said updated image based on changes between said first image or an update of said first image and said undersampled set of projections. The invention further relates to particular uses of the method and a system for radiologically guiding medical interventions on an object, comprising means to provide a first image of the object; an imaging apparatus measuring undersampled sets of projections; processing means in communication with the imaging apparatus for providing updated images on-the-fly during the intervention by reconstructing said updated image based on changes between said first image or an update of said first image and said undersampled set of projections.

Abstract: The invention relates to a circuit for a system for contactless, inductive power transmission, in particular for use in supplying power to mobile devices, and to an associated charging circuit. The circuit comprises a primary-side circuit, which is disposed on a primary side and can be connected to a primary-side supply voltage, and a secondary-side circuit, which is disposed on a secondary side and can be connected to a load to be supplied with power. Furthermore a transformer stage having galvanic isolation is provided for the contactless transfer of power from the primary side over an air gap to the secondary side, wherein at least two magnetically coupled coils are provided for inductive power transmission and can be spatially separated from one another by distancing the secondary side from the primary side. The transformer stage has a resonant converter and the secondary-side circuit further comprises a restabilisation stage.

Abstract: An X-ray detector for recording an image of an object that is moving relative to the detector includes a plurality of detector modules which are adjacently disposed so that they partially overlap. Using the detector modules, a TDI (Time Delayed Integration) is performed within each detector module. Subsequently an evaluation unit determines corrected measurement values of an overlap region by adding the measured values from the individual detector modules in the overlap region.

Abstract: A magnetic resonance system has a basic magnet that generates a static basic magnetic field in an examination volume, and a whole-body antenna that emits a homogeneous radio-frequency field in the examination volume, the homogeneous radio-frequency field exhibiting an excitation frequency so that nuclei in an examination subject in the examination volume are excited to emit magnetic resonance signals, and a radio-frequency shield. The radio-frequency shield is arranged between the whole-body antenna and the basic magnet. The whole-body antenna is arranged between the radio-frequency shield and the examination volume. The radio-frequency shield is fashioned to exhibit a high shielding effect in a shielding frequency range that encompasses the excitation frequency. The shielding effect drops to a significantly lower shielding effect on both sides at side bands adjoining the shielding frequency range.

Abstract: A photon detector has a photocathode for the photon-induced triggering of measuring electrons. Spatial position information is supplied by an at least one-dimensional electron-detector pixel array. An electron optics unit serves for guiding the measuring electrons to the array. Each pixel (19) has an electronic converter unit (20) for converting an analog measuring signal of the pixel (19) into a digital measuring signal, which incorporates a discriminator for background suppression. An electronic post-processing unit (39) serves for processing the digital measuring signal. The converter unit (20) of each pixel (19) has at least one clock generator (36), as well as at least one counter (29, 30), which is in signal connection with the clock generator (36) and discriminator (27) for generation of a digital timing signal.
