Reconstruction of magnetic resonance images (MRIs) by backprojection, which commonly uses techniques analogous to those employed for X-ray computed tomography, is discussed. The recently developed method of linogram reconstruction, an alternative to conventional/backprojection methods of reconstruction from projections, has been adapted for MRI, taking advantage of MRI's flexibility in choosing projection geometry. By avoiding the computationally intensive interpolations required for backprojection, linograms offer significant savings in reconstruction time over conventional backprojection and may offer a slight improvement in resolution as well
