Summary0004409: CT images acquired with gantry tilt are loaded incorrectly

CT images acquired with gantry tilt are loaded incorrectly, probably the gantry tilt information is ignored. The image appears to be warped.

See for example this discussion:

Workaround: use a tool that can convert gantry-tilted DICOM to rectified image files. For example: dicomtonifti tool. Download from here:

Potential implementation: use vtkDICOM classes.

TagsNo tags attached.

Target is 4.9, then if it is stable enough, it could be backported to the 4.8 maintenance branch.

Closing. Corresponding changes were integrated in r26500 and r26501

ENH: model DICOM acquisition geometry (addresses 0004409)

ENH: only issue one convergence warning for inverse transform

I've improved transform hardening on volume nodes recently, so that the output volume is not cropped anymore but extended enough to contain the entire transformed input. Users can use this to apply the acquisition transform. ITK-based resample modules cannot apply the acquisition transform, as it is an inverse transform.
