摘要:
A magnetic resonance apparatus disposed in an installation space has a first component group, which contain at least a basic field magnet system and a gradient coil system, a second component group, which contains an examination volume for receiving an object under investigation and which has at least one supporting device for bringing the object under investigation supported thereon into the examination volume, and sound insulation arranged between the first and second component groups so that the installation space is divided into two spaces which are sound-insulated from each other, a first of the spaces containing the first component group and a second of the spaces containing the second component group.
摘要:
In a method for the operation of a magnetic resonance apparatus, a prescribable event that can trigger a neural activity of an examination subject is initiated, the implementation of the event and the readiness of the examination subject to perceive the event that triggers the neural activity are monitored, and given a positive result of the monitoring, an image dataset of a region of the examination subject to be imaged, and to which the event can be allocated, is registered.

In an apparatus for the recognition of pneumothorax using thorax MR exposures, an evaluation device segments the image of the rib cage, including its surroundings, and characterizes a zone detected between rib cage and lung, preferably in the exhaled condition, that has an MR signal elevated by a prescribed safety margin compared to the noise signal in air.
摘要:
An additional apparatus for a control device for a magnetic resonance tomography apparatus converts an output signal emitted by the control device from an initial frequency into a second frequency. Magnetic resonance signals are excited by the modified output signal. The excited magnetic resonance signals are received. The auxiliary apparatus converts the reception signal back into the initial frequency.
摘要:
In a magnetic resonance apparatus having vertically spaced pole shoes with an examination space therebetween and with an illumination system for illuminating at least a part of an examination space, the illumination system includes a light source arranged outside the examination space and a lightguide having a first end optically coupled to the light source. The lightguide extends above the examination space up to a symmetry line of the examination space. Deflection optics are optically coupled to a second end of the lightguide that lies opposite the light source. The deflection optics deflects the light rays emerging from the second end downwardly in a vertical direction. The lightguide is formed by a bundle of optical fibers which are arranged side-by-side in a flat arrangement on the upper pole shoe so as to reduce the height of the examination space only insignificantly.
摘要:
Normally a cathode ray monitor cannot be employed in a chamber which is shielded against high-frequency interference because of the disturbances in the otherwise shielded chamber produced by the operation of the cathode ray monitor. A display arrangement employing a cathode ray monitor is disclosed, which can be used in a shielded chamber, including a projection picture tube disposed outside of the shielded chamber, a projection disposed inside of the shielded chamber, and an optical imaging arrangement disposed in the beam path between the projection picture tube and the projection screen, the beam path extending through a light-transmissive port in a wall of the shielded chamber.

In a method to obtain measurement data from the stomach of a patient using an endoscope, a degassed aqueous drink solution is administered to the stomach of the patient and the measurement data are acquired with the degassed aqueous drink solution present in the stomach.
摘要:
An endoscopy system has an endo-robot that is navigable within an anatomical lumen of a patient by interacting with a magnetic field generated by an extracorporeal magnet system. The patient lies on a patient bed that is movable in one or more directions and/or orientations, and an obstacle detects objects in the movement path of the endo-robot in the anatomical lumen and produces a signal that causes the position and/or orientation of the patient bed to be altered dependent thereon.
摘要:
An endoscopic capsule has a biocompatible capsule housing that contains at least one sensor device for acquiring medical data. The sensor is arranged on an outer surface of the housing, and has a first electrode produced of an acid-resistant noble metal, and a second electrode produced of silver. An electrical voltage is applied between the first and second electrodes, and a change in an electrical variable is measured between the first and second electrodes when ammonia is present. The endoscopic capsule allows screening of gastric acid and the tissue of the stomach lining for Helicobacter pylori in a manner that is gentle for the patient.
