Abstract
A magnetic resonance imaging (MRI) method is described. The method includes simultaneously acquiring partial radial backprojection signals from a cylindrical array of m detectors surrounding an object, generating, in a k-space, additional backprojection signals with decimated b-fold backprojection steps. The generating includes producing 2-dimensional (2D) spatial harmonics to replace the decimated b-fold backprojection steps. The producing includes assuming that a sum of weighted sensitivity profiles of at least one of the detectors is a function of an angle between a vector k and an axis k of the k-space and a function of a radius of a cylindrical surface formed by the array of detectors. The angle is an angle along which reconstruction of an image of the object is performed.
