mrpro.phantoms.coils.birdcage_2d(number_of_coils: int, image_dimensions: SpatialDimension[int], relative_radius: float = 1.5, normalize_with_rss: bool = True) → Tensor[source]

Numerical simulation of 2D Birdcage coil sensitivities.

This function is strongly inspired by ISMRMRD Python Tools [ISMc]. The associated license information can be found at the end of this file.

Parameters:

  • number_of_coils – number of coil elements

  • image_dimensions – number of voxels in the image This is a 2D simulation so the output will be (1 number_of_coils 1 image_dimensions.y image_dimensions.x)

  • relative_radius – relative radius of birdcage

  • normalize_with_rss – If set to true, the calculated sensitivities are normalized by the root-sum-of-squares
