Hi,
First of all, thank you for the great tools you made available for the
community. I'm currently using dcm2nii to convert dicom files to nifti for
my project : http://vnat.gforge.inria.fr
We experience a problem when we convert some dicom multi-echo images : the
echo time is saved into the nifti header (we can see that with MRicrond) but
it seems that just the decimal value is saved, not the float value.
I provide the files for which I encounter some problems :
https://transfert.inria.fr/fichiers/7a391ed1e8f1e5af7608f89795851fcb/Diffusion%207%20echos.zip
The set of images I used is a 7-echo MR serie and dcm2nii works well as it
produces 7 nifti files. The problem is about the truncation of the echo times :
Echo number - Dicom Echo Time - Nifti header TE (TE should be strictly
equal to the dicom echo time)
1 - 13.8 - ?TR:4530.000 TE:13
2 - 27.6 - ?TR:4530.000 TE:27
3 - 41.4 - ?TR:4530.000 TE:41
4 - 55.2 - ?TR:4530.000 TE:55
5 - 69 - ?TR:4530.000 TE:69
6 - 82.8 - ?TR:4530.000 TE:82
7 - 96.6 -?TR:4530.000 TE:96
Do you know how to solve this problem?
Thank you in advance for your help.
Best regards,
Adrien FERIAL
