deepmr.linops.SenseOp#
- class deepmr.linops.SenseOp(*args: Any, **kwargs: Any)[source]#
Multiply input image by coil sensitivity profile.
Coil sensitivity profiles are expected to have the following dimensions:
2D MRI:
(nsets, nslices, ncoils, ny, nx)
3D Cartesian MRI:
(nsets, nx, ncoils, nz, ny)
3D NonCartesian MRI:
(nsets, ncoils, nz, ny, nx)
where
nsets
represents multiple sets of coil sensitivity estimation for soft-SENSE implementations (e.g., ESPIRIT), equal to1
for conventional SENSE andncoils
represents the number of receiver channels in the coil array.Methods
__init__
(ndim, sensmap[, device, multicontrast])Initiate the linear operator.
forward
(x)Forward coil operator.
to
(*args, **kwargs)Copy to different devices
Attributes
H
Return adjoint linear operator.
