Abstract: An arrangement for supporting a patient in a magnetic resonance apparatus includes a platform that accommodates the patient for a magnetic resonance examination to be conducted, local coils for the magnetic resonance examination and fastening belts, with the fastening belts being fashioned to affix the local coils on the patient and the local coils are at least partially integrated into the respective fastening belts.

Abstract: A combined positron emission tomography/magnetic resonance imaging apparatus for imaging organs of an examination object in an examination space is disclosed, including a positron emission tomography apparatus having at least one radiation detector, and a magnetic resonance imaging apparatus having at least one gradient coil and a radio-frequency antenna device.

Abstract: The present invention discloses a magnetic resonance imaging apparatus for scanning a spine, comprising a body coil for emitting signals, a patient table within the body coil and a spine coil for receiving signals, wherein said spine coil is fixed within said body coil and disposed under said patient table. Said patient table is movable within said body coil by slide rails fitted at the two sides thereof, so as to reduce the length of said spine coil. The cross section of said patient table is in an arched shape, and the cross section of said spine coil is in an arched shape which matches that of said patient table.

Abstract: 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.

Abstract: 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).

Abstract: A magnetic resonance apparatus has a gradient coil unit, which can be displaced on a guide device disposed inside an examination chamber of the magnetic resonance apparatus, an auxiliary device that is displaceable in relation to the examination chamber, and which can be docked on the guide device in order to extend the displacement of the gradient coil unit. The extension device may continue the course of the guide device along a curved path outside of the examination chamber. A positioning device may be displaced on the guide device, extended by the extension device, to displace a subject relative to the examination chamber.

Abstract: A radio-frequency reception arrangement for a magnetic resonance apparatus has a number of independent antennas and pre-amplifiers. The number of pre-amplifiers is less than the number of independent antennas. A switching matrix is arranged between the pre-amplifiers and the antennas for selective, signal-dependent connection of the pre-amplifiers to the antennas.

Abstract: An antenna system for the reception of magnetic resonance signals has at least two resonant individual antennas. The individual antennas are connected to a pre-amplifier via a combination circuit. The combination circuit is fashioned such that signal contributions that can be emitted by the individual antennas exhibit a phase difference of 0° or 180° at the pre-amplifier.

Abstract: An antenna array for magnetic resonance examinations has array elements that are decoupled from each other and that are independent, the array elements being arranged in two adjacent rows. Each array elements is formed by two antenna elements whose respective sensitivity axes reside perpendicular to one another.

Abstract: 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.

Abstract: In a sheath wave barrier, a winding composed of coaxial line is wound in the form of a spiral around an axis. Respective layers of an electrically conductive material that cover both the top and bottom of the spiral winding are respectively disposed at axial spacings from the winding.
