Hi all, I have a set of fiducial points which have the same anterior/posterior coordinates (but different right/left and sagittal coordinates) and I want to be able to show them in the same coronal slice. Despite that I see the same AP coordinates in their .fcsv file, when I load them to Slicer an…

Any suggestions about this ? Thanks.

It is not clear what you want to achieve and what the problem is. A few annotated screenshots and a sample .mrb scene file would help.

Ok, here are some example pics [slicer1] [slicer2] [slicer3] The fiducials you see in the slices have the same anterior coordinates, but despite that, they are shown in different coronal slices. Those coronal slices are really close (seperated by just 0.1 mm), BUT I want to show all of those point…

Slicer shows all markups at +/- half slice spacing distance from the current slice plane. From the images that you attached it seems that your images are not exactly aligned with anatomical axes (the image is slightly rotated). Therefore, slices cut through multiple image slices. Click “Rotate to …

Hmm… Thanks a lot ! Is it possible to obtain the transform matrix for that transformation ? Thank you.

You can get the slice view’s position and orientation as a 4x4 homogeneous transformation matrix by calling GetSliceToRAS() method on the slice node.
