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.
