Dicom import sometimes fails to detect b0 images
Closed, ResolvedPublic
Actions

Description

The problem can occur, that a b0 image will not be recognized as such during DICOM import, for example
DWMRI_gradient_0709:=-0.011180 -0.011180 0.015811
instead of the correct
DWMRI_gradient_0709:=0.000000 0.000000 0.000000

This issue has been known for some time. Trying to compute tensors or qballs will result in crash. Manually changing the gradient to zero will help.

This has been reported by michael bach.

Please confirm if a crash still occurs and set the importance accordingly.
Also, is the reported behavior really random or depending on the image?

Reassigning to Peter, maybe he can comment on whether it still occurs?

Do we have some test data that are known to produce such error?

• hering added a comment.Oct 21 2014, 3:39 PM

The DICOM import recognizes the correct value (as it did before). The reconstruction methods (both q-ball and DTI) produces results, no crash occured. Closing bug.
