class pulserver.mrd.AcquisitionFlag[source]#

Bases: Flag

ISMRMRD acquisition flags as bit masks, combinable with |.

Members are named as the ismrmrd.ACQ_* constants without the prefix. Values are masks, whereas the ismrmrd constants are 1-based bit positions; position and flag give those back. The class does not import ismrmrd.

Examples

>>> import pulserver.mrd as mrd
>>> mrd.AcquisitionFlag.LAST_IN_SLICE.position
8
>>> mrd.AcquisitionFlag.IS_NOISE_MEASUREMENT.flag
'ACQ_IS_NOISE_MEASUREMENT'
>>> either = mrd.AcquisitionFlag.LAST_IN_SEGMENT | mrd.AcquisitionFlag.LAST_IN_SLICE
>>> mrd.AcquisitionFlag.LAST_IN_SLICE in either
True
