1. A magnetic resonance (MR)-positron emission tomography (PET) apparatus, comprising:
a supporting component;
a PET detection device supported on the supporting component;
a radio frequency (RF) coil, wherein the RF coil includes a plurality of coil units arranged around the supporting component, and the plurality of coil units are spaced apart from each other;
a signal shielding component placed between the PET detection device and the RF coil, the signal shielding component being configured to shield the PET detection device from at least part of an RF signal that is generated or received by the RF coil; and
an insulation component, wherein a first side of the insulation component is mechanically attached to the RF coil and a second side of the insulation component is mechanically attached to the signal shielding component.
