Abstract
PET signals are amplified in a hybrid PET/MR system. An amplifier structure is provided for operation in the magnetic field of the MR magnets. By filtering to remove signals at the MR frequency (e.g., about 123 MHz) as part of the amplification circuit, the amplification circuit may be positioned within the RF cabin, within the magnetic field, and even within a same housing as the MR magnets. MR interference may be reduced by staged amplification. The filtering may be bi-directional, such as using parallel and series traps. Digitization of the PET signals may be provided within the magnetic field with no or little interference with MR operation.
