Abstract: In many pump types, in particular in orbital pumps, there is an optimization need with regard to the running characteristics, in particular with regard to parameters which relate to the delivery flow. What is provided is an orbital pump device for delivering liquid medium by a rotational movement including a hydraulic housing surrounding a hydraulic chamber in a fluid-tight manner at least one membrane unit which is arranged inside the hydraulic chamber in flat contact with an inner jacket surface of the hydraulic housing; and an inlet and an outlet provided in the hydraulic housing. At least one crowning is provided at the inner jacket surface and/or at the membrane unit such that a radial gap between the membrane unit and the inner jacket surface is defined by the crowning in a circumferential section of less than 360°, and in particular less than 180°.

Abstract: A method for producing a radio-frequency antenna in a conductor structural element with an encompassing layer sequence, including: providing a rigid carrier having an underside and a top side; defining an antenna assignment section on the rigid carrier; applying at least one electrically insulating layer with a recess in such a way that the antenna assignment section is exposed; placing a radio-frequency substrate above the antenna assignment section with formation of a cavity between the rigid carrier and the radio-frequency substrate; aligning and fixing the radio-frequency substrate relative to the rigid carrier; laminating the layer construction prepared in this manner such that resin material of the at least one electrically insulating layer liquefies and encloses the radio-frequency substrate with the cavity being left free; cutting the antenna assignment section out of the rigid carrier from the outer underside (remote from the layer construction) of the rigid carrier.

Abstract: An arrangement and a method for reducing movement artifacts in spatially resolved magnetic resonance measurements are proposed. A marker system which can emit or reflect at least one electromagnetic ray bundle is permanently connected to a measurement object. The electromagnetic ray bundles emanating from the marker system are projected by means of an imaging system onto spatially separated detector fields and movements of the measurement object are detected by means of the signals of the detector fields and by means of a triangulation method. A correction device generates a correction signal which correspondingly influences the magnetic resonance measurement. Also proposed is a marker system which has a mouthpiece and one or more hollow bodies which can reflect electromagnetic rays and are filled with a material which is visible during a magnetic resonance measurement.

Abstract: An arrangement and a method for reducing movement artifacts in spatially resolved magnetic resonance measurements are proposed. A marker system (138) which can emit or reflect at least one electromagnetic ray bundle is permanently connected to a measurement object (114). The electromagnetic ray bundles emanating from the marker system (138) are projected by means of an imaging system (124, 126) onto spatially separated detector fields (128, 130) and movements of the measurement object (114) are detected by means of the signals of the detector fields and by means of a triangulation method. A correction device (146) generates a correction signal which correspondingly influences the magnetic resonance measurement. Also proposed is a marker system (138) which has a mouthpiece (412) and one or more hollow bodies (310) which can reflect electromagnetic rays and are filled with a material (318) which is visible during a magnetic resonance measurement.
