dcmri.conc_ss#

dcmri.conc_ss(S, TR: float, FA: float, T10: float, r1=0.005, n0=1) → ndarray[source]#

Concentration of a spoiled gradient echo sequence applied in steady state.

Parameters:

  • S (array-like) – Signal in arbitrary units.

  • TR (float) – Repetition time, or time between successive selective excitations, in sec.

  • FA (float) – Flip angle in degrees.

  • T10 (float) – baseline T1 value in sec.

  • r1 (float, optional) – Longitudinal relaxivity in Hz/M. Defaults to 0.005.

  • n0 (int, optional) – Baseline length. Defaults to 1.

Returns:

Concentration inM , same length as S.

Return type:

np.ndarray
