dcmri.signal_dsc#

dcmri.signal_dsc(R1, R2, S0: float, TR, TE) → ndarray[source]#

Signal model for a DSC scan with T2 and T2-weighting.

Parameters:

  • R1 (array-like) – Longitudinal relaxation rate in 1/sec. Must have the same size as R2.

  • R2 (array-like) – Transverse relaxation rate in 1/sec. Must have the same size as R1.

  • S0 (float) – Signal scaling factor (arbitrary units).

  • TR (array-like) – Repetition time, or time between successive selective excitations, in sec. If TR is an array, it must have the same size as R1 and R2.

  • TE (array-like) – Echo time, in sec. If TE is an array, it must have the same size as R1 and R2.

Returns:

Signal in arbitrary units, same length as R1 and R2.

Return type:

np.ndarray
