摘要:
In a radio-frequency receiver unit for a magnetic resonance apparatus, a reception antenna is connected to an input of a noise-matched field-effect transistor preamplifier with a low input impedance. The reception antenna is connected with a detuning stage. The RF receiver unit has a noise suppression stage that can be activated when the reception antenna is detuned.

A voltage equalization device for equalizing voltage fluctuations in a voltage supply is provided. The voltage supply has an electrical voltage that is as constant as possible. The voltage equalization device has at least one transformer unit which has a primary winding unit and a secondary winding unit and, on one of the two winding units, has at least three or more selection units for switching in or switching out turns of the winding unit. Two adjacent selection units are so arranged in each case as to be separated from one another by a distance having a number of turns. The number of turns between two first adjacent selection units is different from the number of turns between two further adjacent selection units.

An illumination device (1,10,20,41) for illuminating an examination room (33) of an imaging medical examination device (31) has illuminants (7,21,55), which emit light when energized and can be electrically connected to a power source via connecting means (5A,5B,15A, . . . 15D), at least two of the illuminants (7,21,55) being connected by means of an electrical supply line (8) and the electrical supply line (8) having at least one high frequency filter (9,11) for reducing the interaction of the supply line (8) with a high frequency field.
摘要:
A module of a support apparatus (5) of a medical examination and treatment device, in particular of a magnetic resonance device (3), comprises the following features: a base unit (52) and a support unit (54) to support an examination object (1), which can travel in the horizontal direction in respect of the base unit (52), and a bracket unit (70) acting between the base unit (52) and the support unit (54), it being possible to move said bracket unit (70) against the base unit (52) and the support unit (54) and with which the support unit (54) can travel beyond the base unit (52).
摘要:
A patient transportation system includes: a patient transportation device configured to dock with a medical instrument, the patient transportation device having a plurality of wheels; a registration apparatus configured to register information; and a control unit configured to change at least one wheel position of at least one wheel of the plurality of wheels based on information registered by the registration apparatus. The system may be used to assist operating staff when the patient transportation device approaches the medical instrument.
摘要:
The invention relates to a support apparatus on which a patient can be supported in a comfortable and secure manner for the preparation for an examination and for the examination, in particular an endorectal biopsy. The support apparatus comprises a sliding apparatus connected to a bearing substructure and is supported in a displaceable manner on the sliding apparatus so that it can be moved partially beyond the substructure connected to the sliding apparatus. The support apparatus also comprises a cutout. The invention also relates to a patient support table comprising a connecting apparatus to connect the patient support table to the support apparatus and serving as a bearing substructure for the support apparatus. A medical device, in particular an MR device, is also disclosed comprising a patient tunnel and the patient support table that can be introduced into the patient tunnel.
摘要:
A simplify mobile patient support apparatus which is suitable for an examination of a patient by a magnetic resonance tomography system is proposed. A first and second actuation facility and a control facility are used. Depending on the operating state of the patient support apparatus whether is docked with or undocked from the magnetic resonance tomography system, actuation of the first and second actuation facilities results either in the coupling or uncoupling of the patient support apparatus to/from the magnetic resonance tomography system or the raising or lowering of a patient support plate of the patient support apparatus. Essential components for docking or undocking or for the vertical adjustment of the patient support plate are integrated in a hydraulic unit.
