摘要:
An apparatus for examining contrast agent movement in the body of a patient under the effect of gravity has an MR scanner with a patient support system which can be tilted around the longitudinal axis and/or transverse center axis for placing the patient in an oblique position within the magnet.
摘要:
The energy supply device for a signal pickup or signal generator for use in or at a magnetic resonance tomography device has a double layer capacitor of high capacitance and high power density. Charging of the double layer capacitor can occur via an integrated charging coil that derives charging energy from the high-frequency and/or gradient fields of the device.
摘要:
In a method and apparatus for calibrating a navigation system in relation to image data of a magnetic resonance apparatus, positions of at least three markers arranged in an imaging volume of a magnetic resonance apparatus are determined with the navigation system in a first coordinate system, and are determined by means of magnetic resonance in a second coordinate system. From the positions of the markers in the two coordinate systems, a position and an orientation of the two coordinate systems to one another are determined. Localization data are transformed into the second coordinate system. An apparatus for conducting the method has at least one marker having a substance that can be detected using magnetic resonance technology, in spatial allocation to optical markings. A pickup coil can be spatially allocated to each marker.
摘要:
In an electrical assembly with an electrical or electronic component part that generates a noise signal with a disturbing frequency, a parallel resonant circuit tuned to the frequency is arranged in the immediate proximity of the component part.
摘要:
Shielding for openings of shielded housings, particularly monitors, has a frame of soft-magnetic material arranged in front of the opening, an electrical coil whose current, controlled by magnetic field sensors, compensates penetrating noise fields in a direction substantially normal to the plane of the opening, with the turns of the coil being located at the inside of the frame.
摘要:
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:
A method is proposed for determining clinical study compliance. The method includes obtaining criteria for the clinical study and accessing stored clinical data relating to the clinical study. Thereafter, the criteria and clinical data are correlated to determine a measure of compliance with the criteria of the clinical study.
摘要:
An endocapsule has a measurement chamber therein containing a sensor that detects at least one metabolic product of a specific bacterium in a hollow organ of a human or animal gastrointestinal tract. The endocapsule is introduced into the hollow organ wherein detection of the at least one metabolic product takes place.
摘要:
In a method and a device to detect information about the three-dimensional structure of the inner surface of a body cavity (2) of a patient with an endoscopy capsule (4) introduced into said body cavity (2), a first partial region of the inner surface of the body cavity (2) is illuminated with at least one light source (16) arranged in the endoscopy capsule (4): and an image of a second partial region (36) that is illuminated by the first partial region (30) and differs from said first partial region (30), the three-dimensional structure of which second partial region (36) is known, is acquired with at least one camera (18) arranged in the endoscopy capsule (4). Information about the three-dimensional structure of the first partial region (30) is derived using the intensity values present in this image.
摘要:
A system for detection, administration and/or evaluation of configuration data describing the hardware or software configuration of different (in particular medical technology) devices has a central database (in particular manufacturer-spanning central database) the configuration data stored therein, which is connected to a network (in particular the Internet via at least one software unit (fashioned as a programming interface and/or Internet platform), which enables a role-specific access to the database via role-based interfaces. An operator role and/or an end user role (in particular a referrer and/or patient role) and/or a manufacturer role are provided as roles.
