xarray.DataArray.kspace.offsets¶

DataArray.kspace.offsets¶

Angle offsets used in momentum conversion.

Returns:: OffsetView – A mapping between valid offset keys and their corresponding offsets.

Examples

View all offsets

>>> data.kspace.offsets
{'delta': 0.0, 'xi': 0.0, 'beta': 0.0}

Offsets to dictionary

>>> dict(data.kspace.offsets)
{'delta': 0.0, 'xi': 0.0, 'beta': 0.0}

Set single offset

>>> data.kspace.offsets["beta"] = 3.0
>>> data.kspace.offsets
{'delta': 0.0, 'xi': 0.0, 'beta': 3.0}

Overwrite offsets with dictionary

>>> data.kspace.offsets = dict(delta=1.5, xi=2.7)
>>> data.kspace.offsets
{'delta': 1.5, 'xi': 2.7, 'beta': 0.0}

Update offsets

>>> data.kspace.offsets.update(beta=0.1, xi=0.0)
{'delta': 1.5, 'xi': 0.0, 'beta': 0.1}

Reset all offsets

>>> data.kspace.offsets.reset()
{'delta': 0.0, 'xi': 0.0, 'beta': 0.0}
