HYBRID PET/MR IMAGING SYSTEMS

摘要

A hybrid imaging system includes a magnetic resonance scanner (10) and a second modality imaging system (12) such as PET or SPECT disposed in the same radio frequency isolation space (16). The second modality imaging system includes radiation detectors (68, 70, 70') configured to detect at least one of high energy particles and high energy photons. In some embodiments a retractable radio frequency screen (92) is selectively extendible into a gap between the magnetic resonance scanner and the second modality imaging system. In some embodiments shim coils (52) are disposed with the magnetic resonance scanner and are configured to compensate for distortion of the static magnetic field of the magnetic resonance scanner produced by proximity of the second modality imaging system.
