摘要： A detector unit for arrangement in a field generating unit of a magnetic resonance device has an RF transmission/reception system for transmitting RF pulses into, or receiving magnetic resonance signals from, an examination volume of the field generation unit. The RF transmission/reception system surrounds a patient tunnel at a radial distance from a tunnel axis thereof, and is divided into two sub-systems located at a distance from each other along the direction of the tunnel axis, so as to form a substantially annular cavity or interstice therebetween.

摘要： An RF antenna arrangement of a combined MR/PET system is disclosed. In at least one embodiment, the RF antenna arrangement includes a first part installed in the examination tunnel in a fashion fixed to the system such that it is arranged underneath the couch board when the latter is introduced, and a second part, which can be placed onto the couch board and be introduced into and withdrawn from the examination tunnel together with the couch board. In at least one embodiment, the second part is of dimensionally stable design and has a clear cross section that is adapted to the object to be examined. Consequently, the time outlay for applying the RF antenna is reduced, and the fixed position of the RF antenna enables a correction of the attenuation of gamma rays. Furthermore, a number of second parts having various diameters can be provided.

摘要： A magnetic resonance antenna has longitudinal antenna rods in a birdcage structure, and antenna ferrules connecting the longitudinal antenna rods at their ends in terms of radio-frequency. The magnetic resonance antenna has a number of radio-frequency switching elements that interrupt, in terms of radio-frequency, at least one part of the longitudinal antenna rod to detune the eigen-resonance frequency of the antenna with respect to an operating magnetic resonance frequency. For this purpose, the magnetic resonance antenna is provided with two switching lines, directed to the radio-frequency switching elements from outside of the birdcage structure, the switching lines having a ring line connected thereto running annularly on or in the birdcage structure and transverse to the longitudinal antenna rods.
