extras.field_map

Field map Module.

This module provides methods to generate dummy B0map as well as estimation of the bilinearization of the off-resonance model (See Off-resonance correction model for a detailed explanation).

Functions

compute_mfi_coefficients	Compute off-resonance correction coefficients using Mixed-Frequency-Interpolator.
compute_mti_coefficients	Compute off-resonance correction coefficients using Mixed Time interpolator (MTI).
compute_svd_coefficients	Compute off-resonance correction coefficients using an SVD.
get_complex_fieldmap_rad	Create a complex-valued field-map in rad/s.
make_b0map	Make radial B0 map.
make_t2smap	Make homogeneous T2* map.

Classes

C_lazy

A lazy version of the C interpolator.
