There exists an ever increasing need to design and build medical imaging systems that are capable of obtaining PET-MRI images in conjunction. This work describes minimum stored energy superconducting magnet coil arrangements for the purpose of a combined PET-MRI scanner. Two symmetric magnet coil configurations are used, similarly to the double doughnut systems, with space between them allowing for the insertion of a PET camera. The final design is capable of delivering 3T, which is appropriate for animal MRI. The results show that the minimum stored energy approach yields a compact configuration with a small footprint.
