There 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.
