deepmr.bloch.T2Prep#
- deepmr.bloch.T2Prep(Tprep, T1, T2, weight, k, prep_props)[source]#
T2 prep operator.
Consists of a 90°-180°–90° composite pulse followed by a crusher gradient.
- Parameters:
Tprep (torch.Tensor) – T2 preparation time in
[ms].T1 (torch.Tensor) – T1 relaxation time of shape
(..., npools) in ``[ms].T2 (torch.Tensor) – T2 relaxation time of shape
(..., npools) in ``[ms].weight (torch.Tensor) – Pool relative fraction.
k (torch.Tensor) – Chemical exchange matrix
(...., npools, npools)in[Hz].prep_props (dict) – Extra pulse parameters.
- Returns:
PrepPulse – Adiabatic T2prep pulse operator, including crusher.
- Return type:
deepmr.bloch.Operator
