Abstract:
1. A method for a medical examination using a magnetic resonance imaging (MRI) machine having an object positioned therein, said method comprising: polar phase encoding to generate a plurality of signals forming datasets representative of the object by frequency encoding in a Z-direction of a k-space, wherein the datasets form an elliptical grid in polar coordinates in the k-space, the Z-direction substantially parallel to a center axis of the elliptical grid, wherein said phase encoding comprises phase encoding in which each datum is represented as m(a cos(2πd/n)kx+b sin(2πnd/n)ky+ickz, a, b, c, and d are real numbers, m, n, and i are an integers, and kx, ky, and kz being unit basis vectors in the k-space; forming a nested loop by: outputting an image of the object generated using the datasets.
