mrpro.algorithms.csm.inati(coil_img: Tensor, smoothing_width: SpatialDimension[int] | int) → Tensor[source]

Calculate a coil sensitivity map (csm) using the Inati method [INA2013] [INA2014].

This is for a single set of coil images. The input should be a tensor with dimensions (coils, z, y, x). The output will have the same dimensions. Either apply this function individually to each set of coil images, or see from_idata_inati which performs this operation on a whole dataset.
