Cartesian undersampling for 2D about bart

[hcmh]

Hi Georg,

such questions are better placed on the mailing list:

https://lists.eecs.berkeley.edu/sympa/info/mrirecon

as a question is not an issue with bart.

As to your question: for regular Cartesian undersampling, there is upat. However, in the paper you linked, they are using random Cartesian undersampling in 1D. For this, I think the only way to do it with bart tools is using poisson with bart poisson -Z1 (so, setting one of the dimensions to 1), and then adding a calibration region by hand.

If you want more specific answers, please use the mailing list.

Best regards,
Christian
