Hi,

I am working with some chest CT scans and I have some `fiducials`

which denote the 3D centre of a tumour mass. I have saved/exported the `fiducials`

from Slicer as `.fcsv`

files.

I have done some searching online but I am not entirely sure how to convert the `fiducial`

coordinates (in mm) from `RAS`

to `LPS`

using `Slicer`

(assuming its possibile). Hoping someone can point me in the right direction.

Also, if anyone here has any general resources they could point me towards to better understand RAS to LPS (and vice versa) geometric transformations, that would be greatly appreciated. Always looking to better understand these concepts.

Thanks,

Matt
