Abstract: A stator-less electric motor for an MRI system is provided. The stator-less electric motor includes a body, a rotor rotatable connected to the body, and at least one coil winding disposed on the rotor. The at least one coil winding is arranged so as to rotate the rotor when energized via an electrical current in the presence of a magnetic field generated by a magnet assembly of the MRI system.

Abstract: A radio frequency coil includes a body having an inner wall and an outer wall opposite the inner wall. The body is configured to fit over an imaging bore of a magnetic resonance imaging system such that the inner wall is closer to the imaging bore than the outer wall. The body may have a cooling duct embedded in the body between the inner wall and the outer wall and configured to direct a coolant to at least one assembly component disposed in the magnetic resonance imaging system. The cooling duct may be formed by the body. A phase change material may be disposed on the body or embedded in the body between the inner wall and the outer wall. The phase change material may be configured to absorb heat emitted by at least one assembly component of the magnetic resonance imaging system.

Abstract: A PET-MRI system for imaging an object is provided. The PET-MRI system includes a magnetic resonance imaging sub-system, a positron emission tomography sub-system, an optical sensor, and a data processing controller. The magnetic resonance imaging sub-system includes a surface coil that acquires magnetic resonance signals from the object. The positron emission tomography sub-system acquires PET emissions from the object. The optical sensor detects at least one of a spatial location and a shape of the surface coil. The data processing controller communicates with the magnetic resonance imaging sub-system, the positron emission tomography sub-system, and the optical sensor, and utilizes at least one of the detected spatial location and the detected shape of the surface coil to correct the acquired PET emissions for attenuation.
