    摘要: A magnetic resonance apparatus has an integrated gradient and radio frequency coil unit that includes at least one antenna rod with a conductor and a gradient coil unit. At least one electrical connection exists between the conductor and an electrical contact region arranged at an adjoining region of the gradient coil unit. The electrical connection is formed by a flexible circuit board that is electrically connected both with the conductor and with the contact region. Such an electrical connection of the antenna rod is insensitive to strong vibrations.

    摘要: Combined positron emission tomography and magnetic resonance tomography unit for imaging an examination object in an examination space, comprising a positron emission tomography unit that has a unit part assigned to the examination space, and a first evaluation unit for evaluating the electric signals for a positron emission tomography image of the examination object. The unit part in this case comprises a gamma ray detector with an assigned electronics unit. Furthermore, the combined unit comprises a magnetic resonance tomography unit and a second evaluation unit for evaluating the magnetic resonance signals for a magnetic resonance image of the examination object. The magnetic resonance unit in this case has a high frequency antenna device as well as a gradient coil system, the high frequency antenna device being arranged nearer to the examination space than the gradient coil system, as well as a high frequency shield arranged between the gradient coil system and the high frequency antenna device. The positron emission tomography unit part is arranged in this case between the high frequency shield and the high frequency antenna device, and is provided, at least on the side facing the high frequency antenna device, with a shielding cover that is caused by the high frequency antenna device and is opaque to high frequency radiation.

    摘要: A magnetic resonance system has a transport element and an examination tunnel with an inner tunnel contour and a tunnel axis. An examination subject can be inserted into the examination tunnel in the direction of the tunnel axis by means of the transport element. At least one local coil that exhibits an outer coil contour (viewed in cross-section relative to the tunnel axis) and that can be pivoted around a base pivot axle, so as to be adjusted to the examination subject, is disposed in the examination tunnel. The base pivot axle is disposed at the edge of the examination tunnel and runs parallel to the tunnel axis.

    摘要: A generator of time-variable magnetic fields generator for a magnetic resonance apparatus has a primary gradient coil unit for generating of a gradient magnetic field in an examination region of the magnetic resonance apparatus. The primary gradient coil unit, for accommodating at least one gradient coil conductor, has a central region, an outer region and at least one connecting region connecting the two regions. The outer region surrounds the central region. At least one intervening space is disposed between the central region and the outer region. The intervening space is free of the gradient coil conductors of the primary gradient coil unit and a radio frequency antenna element is disposed therein. Such a generator enables an effective gradient field and RF field generation in a compact design combining a gradient coil and a radio-frequency antenna.

    摘要: A gradient coil radio-frequency antenna unit for a magnetic resonance apparatus has a radio-frequency antenna and a plate-shaped gradient coil unit to generate a gradient magnetic field in an examination region of the magnetic resonance apparatus. The gradient coil unit is surrounded by a conductor of the radio-frequency antenna. The windings of the gradient coil unit thus lie completely within the conductor of the RF antenna.

    摘要: A coil arrangement for a magnetic resonance system has a resonator that is followed by a modulator with which a magnetic resonance signal of the resonator is modulated onto a carrier frequency. An infeed element follows the modulator with which that magnetic resonance signal modulated onto the carrier frequency is supplied into a single transmission cable. In a corresponding reception circuit, an analog-to-digital converter is preceded by a demodulator with which the magnetic resonance signal is demodulated.

    摘要: A magnetic resonance tomography apparatus has a basic field magnet system and a gradient coil system. At least a part of a vacuum housing of an evacuatable space is thereby formed by at least a surface region of the basic field magnet system and by at least a surface region of the gradient coil system. Propagation of oscillations (vibrations) of the gradient coil system to the basic field magnet system via an intermediate layer between those surfaces of the gradient coil system and of the basic field magnet system that face each other is prevented by a vacuum in the evacuatable space. In economical and space-saving fashion, the vacuum housing of the evacuatable space is formed to a large part by systems that are already needed for the operation of the apparatus.
