SPM/Slice Timing

The ProblemEdit

With an EPI sequence, slices constituting a 3D volume are acquired at different times (within one TR).

Slice Timing CorrectionEdit

See SPM > Temporal > Slice Timing.

Slice OrderEdit

hdr = spm_dicom_headers('dicom.ima');
slice_times = hdr{1}.Private_0019_1029

Timing ParametersEdit

See Microtime Onset and Microtime Resolution.

Using the HRF Time DerivativeEdit

See HRF 'Informed' Basis Set.
