Method for homogenising resolution in magnetic resonance tomography recordings using non-linear encoding fields

摘要

The method involves applying non-linear gradient fields for spatial encoding, and completely imaging an object in regions of stronger gradient fields by increasing density of sample points in center of a k-space. Additional sampling points are acquired in outer regions of the k-space with respect to a k-space sampling pattern and depending on a desired distribution of a resolution. A magnetic resonance (MR) imaging result is calculated by using the additional sampling points. The sampling pattern is composed of sub patterns, where each sub pattern comprises an equal number of sample points.
