Hello,  
I’m anonymizing several CT using the _SlicerBatchAnonymize_ extension. It works well except for one CT.  
I can load the CT manually using the DICOM data module without any issue.

I get the following errors :

```auto
[VTK] Size mismatch! The size of C:/path/000000.dcm is [512, 512, 563] and does not match the required size [512, 512, 1] from file C:/path/000000.dcm

```

I don’t know if it’s relevant but when I load the CT throught the DICOM database, it get the mention _- imageType ORIGINAL-PRIMARY-AXIAL_
