Hi, I have been performing tractography with Slicer 4.10.2 (Windows). I have to say the results have been super impressive.I would like to know how slicer deals with multiple b0 scans.
I have 63 volumes. Under “Volumes” module with the “DWI Component” slider, I see the b0 volumes are at #0, 31, and 62. The scans were done under sedation and there is no clearly detectable movement or eddy artifact.
– Does slicer average these b0 volumes?
If not, how can I do that?
– I am new to DTI, and I hope to publish my data. Is there a reference to the standard methodology that 3Dslicer uses? I am guessing it is not TBSS? I will also be checking my results with UKF, but should I just go right to UKF? My subjects have known white matter disease in the context of metabolic / mitochondrial disorders.
Lastly (and not a big issue) when converting exported DICOM diffusion volumes from the NilRead viewer, I get a lot of these errors:
Diffusion-weighted DICOM Import (DWIConvert) standard error:
E: can’t change to unencapsulated representation for pixel data
E: can’t determine ‘PhotometricInterpretation’ of decompressed image
E: mandatory attribute ‘PhotometricInterpretation’ is missing or can’t be determined…
Is that because the DICOM download needs a special header for 3DSlicer?
Thanks very much for your help.
