Description

technical field

[0001] The invention relates to a detection unit for placement in a cylindrical patient chamber of a magnetic resonance system, comprising an annular PET detector arrangement with a PET detector part and a coaxially arranged PET detector arrangement with a long High-frequency coil devices for conductors. Background technique

[0002] Magnetic resonance tomography (MRT) and positron emission tomography (PET) are both imaging methods for visualization of the interior of the human body and, in particular in the case of PET, for visualization of biochemical processes. There is current interest in combining MRT with PET in one device so that both imaging modalities can be used simultaneously or in short succession on the same patient.

[0003] For this purpose, it is proposed to arrange, if necessary, removable PET detectors within the magnet arrangement of the magnetic resonance system consisting of the basic field magnet and the gradient coils. The radio-frequ...
