Transform for noise for MRI #7815

Open karllandheer opened 4 weeks ago

karllandheer commented 4 weeks ago

Hello, would it be possible to add noise for MRI? Specifically, modern MRI uses multiple coils which results in a non-central chi distribution for the noise (https://en.wikipedia.org/wiki/Noncentral_chi_distribution), which is a generalization of Rician noise (i.e., for a single quadrature coil they're the same). Today, nearly all (maybe all?) human scans are received with multiple coils. Probably all large brain datasets are received with multiple coils. For brain, for example, 32-64 is the standard today. Thanks very much for your great package!
