Raw MRI data are generated analytically from k-space coordinates using the (continuous) Shepp and Logan head phantom function. K -space coordinates are typically entered as 2D matrices (frequency and phase encodes).

This tool is ideal for testing reconstruction of non-linear k-space trajectory MRI data such as projection reconstruction (PR) and spiral PR MRI.

The default k-space trajectory is a simple Carthesian trajectory. The reconstruction of the image in this case is a simple 2D FFT. Running the scripts without arguments results in plots of the raw and reconstructed data for this k-spce sampling path.
