Extracting TotalReadOutTime from Siemens XB DICOM files

Dear dcm2nii Team,


We have recently upgraded our scanner to a Siemens 7T Terra X with the new XB software Platform.


Unfortuantely dcm2nii does not appear to extract information from the DICOM on TotalReadOutTime (and/or Effective Echo Spacing + ReconMatrixPE for it's calculation) for use with FSL Topup.


I was wondering if there was a solution to this or whether this was a known issue?


Any help would be greatly appreciated


Best Wishes,


Dr Stuart O'Connor

1. XB10 is a new release. Can you make sure you are running v1.0.20260724 which was validated on XB10 data (albeit a 3T Vida).

2. It might be worth knowing the sequence where readout time is not provided. In particular, you will need the latest version of dcm2niix to read details from the ep3d research sequences.

3. If thse do not resolve your problem, I suggest creating a Github issue and providing steps to replicate.
