"O-space" projection imaging using a combination of linear gradients and the Z2 spherical harmonic is described. Gradient encoding functions are chosen so as to complement the information provided by a circumferential array of surface coils. Using the resulting hybrid encoding function, images are reconstructed from simulated data using the Kaczmarz iterative algorithm. The O-space results show better resolution and lower artifact levels than undersampled radial k-space data, demonstrating that valuable spatial information is provided by the addition of the Z2 field.
