We developed two large bore (30 and 40 mm diameter) gradient coil probes for a vertical wide bore superconducting magnet (4.74 T) with solenoid coils. The planar gradient coils were designed using the genetic algorithm, which optimized power consumption under the restriction that the linearity of the magnetic field gradients is less than 10% within the target volume (30 and 40 mm diameter sphere). The gradient probes were evaluated using a 3D lattice phantom and plant samples, which demonstrated the usefulness of the developed gradient probe.
