Abstract

A method of MR imaging applies a magnetic field Bgrad1 having a spatially non-linear dependence to select a volume of at least one curved slice. The slice is described by its midsurface AM, a volume of the selected slice being made up of nν partial volumes in each of which gradients of at least one pair of remaining superimposed magnetic fields Bgradi (i>1) exhibit an angle dependence of 70° to 110° with respect to one another and with respect to the normal of the midsurface AM. At least one superimposed magnetic field of the respective pair exhibits a spatially non-linear dependence and combinations of these pairs are used for spatial encoding. In this way, curved surfaces can be mapped efficiently in high resolution and the method can be adapted to the slice shape.
