dcmri.conc_ss

dcmri.conc_ss(S, TR, FA, T10, r1=0.005, n0=1, S0=None)

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 (array-like) – 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
