Perform simple analytical Fast Spin Echo simulation.

Assume that refocusing angles are 180° and k-space center is sampled for each echo in the Echo Train (e.g., as in spiral or radial imaging).

Parameters:

  • M0 (np.ndarray) – Input equilibrium magnetization.

  • T1 (np.ndarray) – Input T1 in [ms].

  • T2 (np.ndarray) – Input T2 in [ms].

  • TE (float | Sequence[float]) – Sequence Echo Time in [ms].

  • TR (float | Sequence[float]) – Sequence Repetition Time in [ms].

Returns:

signal – Simulated signal of shape (nTE*nTR, *M0).

Return type:

np.ndarray
