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

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.
Thank you very much for your job.It is excellent.
Thanks. I want to take input coil data in image domain for parallel imaging operation. How will I find the database for giving as inputs to different coils?
Thank you for this excellent job. Really helpful.
