is an increasing need to design and build systems that are capable of
acquiring different modality medical images. This work describes a method of
simulation of gradient coils which are appropriate for use in PET-MRI
scanners. The proposed gradient coil with a gap in the middle has windings
wrapped into the transverse plane at the edges for improved gradient fields.
The design is developed for animal scanners with an inner bore size of 40cm.
The gradient coil winding pattern, magnetic field produced and error in the
gradient magnetic field are provided to establish quality of design.
