Patent ID: 7323874

Claim:
A combined positron emission tomography and magnetic resonance tomography unit for imaging an examination object in an examination space, comprising a positron emission tomography unit having a unit part assigned to the examination space, the unit part comprising at least two gamma ray detector units with in each case an assigned electronics unit for detecting radiation emitted from the examination space of the examination object and converting the radiation into corresponding electric signals, and a first evaluation unit for evaluating the electric signals for a positron emission tomography image of the examination object; and a magnetic resonance tomography unit, including a high frequency antenna device for at least one of transmitting high frequency excitation pulses into the examination space and receiving, from the examination space, magnetic resonance signals from the examination object, the high frequency antenna device being formed as a stripline antenna device having at least two conductors, each conductor of the stripline antenna device respectively including a gamma ray detector unit with an assigned electronics unit for which the conductor forms a shielding cover opaque to high frequency radiation caused by the high frequency antenna device, a gradient coil system for generating magnetic gradient fields in the examination space, the high frequency antenna device being arranged nearer to the examination space than the gradient coil system, a high frequency shield arranged between the gradient coil system and the high frequency antenna device, for decoupling the high frequency antenna device from the gradient coil system, and a second evaluation unit for evaluating the magnetic resonance signals for a magnetic resonance tomography image of the examination object.
