VTI Reslice Cursor Widget center in millimeters

Web
1

Hey,
I am facing some difficulties getting center of the reslice cursor widget state, in millimeters, (my VTI file is exported from DICOM series using dicom-exporter)

Does the center values of the reslice cursor widget state mean the center of the whole image or the center of the brain?

I don’t know what is the actual unit of measurement and I need to get the locations that the reslice cursor points to in millimeters (Sorry I’m new to vtk.js)
Here is what I’m getting on every onInteractionEvent after calling console.log(widget.getWidgetState().getCenter());

The unit is the same as the unit of your DICOM file.

The center is typically expressed in milimeters.
You may have to compare it relative to the “origin” (lower left corner) of your image.

I’m not sure why it the center does not move. It might be that onInteractionEvent is triggered three times, once for each plane…
