bartorch.nlop.CartesianSense()#

Cartesian joint image and coil-sensitivity forward model.

NonlinearSense on a grid, the model nlinv inverts without a trajectory: the nonlinear counterpart of bartorch.linop.CartesianSense(), with the sensitivities a second unknown.

Parameters:

  • image_shape (tuple of int) – Coil-image shape (coils, *spatial), C order.

  • pattern (torch.Tensor, default=None) – Sampling mask; None is fully sampled.

  • **kwargs – Keyword arguments of NonlinearSense, except trajectory.

Returns:

Inputs: image, coil coefficients. Output: k-space.

Return type:

NonlinearSense

Raises:

ValueError – If trajectory is given.
