Fit a T2 relaxation curve, from multiple TEs, to a set of amplitudes.

Description

Fit a T2 relaxation curve, from multiple TEs, to a set of amplitudes.

Usage

fit_t2_te_array(
  te_vec,
  amp_vec,
  lower = 0,
  upper = 10,
  output_fit_res = 0.01,
  ret_full = TRUE
)

Arguments

te_vec	vector of TE values in seconds.
amp_vec	vector of amplitudes.
lower	minimum allowable T2 value.
upper	maximum allowable T2 value.
output_fit_res	temporal resolution (seconds) of the ideal output relaxation curve.
ret_full	return full fitting information including ideal relaxation curve.

Value

a list containing relaxation parameters and an ideal curve for fit evaluation.
