  • Definition: The time in seconds between the beginning of an acquisition of one volume and the beginning of acquisition of the volume following it (TR). When used in the context of functional acquisitions this parameter best corresponds to DICOM Tag 0020,0110: the 'time delta between images in a dynamic of functional set of images' but may also be found in DICOM Tag 0018, 0080: 'the period of time in msec between the beginning of a pulse sequence and the beginning of the succeeding (essentially identical) pulse sequence'. This definition includes time between scans (when no data has been acquired) in case of sparse acquisition schemes. This value MUST be consistent with the 'pixdim[4]' field (after accounting for units stored in 'xyzt_units' field) in the NIfTI header. This field is mutually exclusive with VolumeTiming.

Use RepetitionTimeExcitation (in combination with RepetitionTimePreparation if needed) for anatomy imaging data rather than RepetitionTime as it is already defined as the amount of time that it takes to acquire a single volume in the task imaging data section.

A - sign indicates that the contents of SliceTiming are defined in reverse order - that is, the first entry corresponds to the slice with the largest index, and the final entry corresponds to slice index zero. When present, the axis defined by SliceEncodingDirection needs to be consistent with the ‘slice_dim' field in the NIfTI header.

  • Label: 'SliceTiming'
  • Definition: The time at which each slice was acquired within each volume (frame) of the acquisition. Slice timing is not slice order -- rather, it is a list of times containing the time (in seconds) of each slice acquisition in relation to the beginning of volume acquisition. The list goes through the slices along the slice axis in the slice encoding dimension (see below). Note that to ensure the proper interpretation of the SliceTiming field, it is important to check if the OPTIONAL SliceEncodingDirection exists. In particular, if SliceEncodingDirection is negative, the entries in SliceTiming are defined in reverse order with respect to the slice axis, such that the final entry in the SliceTiming list is the time of acquisition of slice 0. Without this parameter slice time correction will not be possible.
