Echo Time Time in ms between the middle of the excitation pulse and the peak of the echo produced (kx=0). In the case of segmented k-space, the TE(eff) is the time between the middle of the excitation pulse to the peak of the echo that is used to cover the center of k-space (i.e.,-kx=0, ky=0). DICOM:0018_0081 term ILX:0103661 24156.34 DICOM term, Project role, Role, Realizable entity, Specifically dependent continuant, Dependent continuant, Continuant
Effective Echo Time The time in ms between the middle of the excitation pulse and the peak of the echo produced for kx DICOM:0018_9082 term ILX:0103680 450.34576 DICOM term, Project role, Role, Realizable entity, Specifically dependent continuant, Dependent continuant, Continuant
Effective Echo Spacing The effective sampling interval, specified in seconds, between lines in the phase-encoding direction, defined based on the size of the reconstructed image in the phase direction. ILX:0739317 term ILX:0739317 275.32852
Dwell Time Actual dwell time (in seconds) of the receiver per point in the readout direction, including any oversampling. For Siemens, this corresponds to DICOM field (0019,1018) (in ns). ILX:0739327 term ILX:0739327 200.70322
