Parallel MRI noisy phantom simulator
PHANTOM_PARALLEL simulates a noisy multiple coil acquisition of a synthetic MR image. The inputs are an MR slice, the number of coils, the covariance matrix and the configuration of the parallel acceleration.
It allows three kind of outputs:
- Multiple-coil without k-space subsampling.
- With subsampling and GRAPPA reconstruction
- With subsampling and SENSE reconstruction.
The output also provides the variant noise patterns and effective values according to

Magnetic Resonance in Medicine. Volume 65, Issue 4, pages 1195–1206, 2011

The toolbox is intended for simulation of realistic noise patterns in MR data for validation of filtering and noise estimation methods. The non-noise data (Golden Standard) is provided in any case.
