Hi Vicky, If you can attached an image with the ROI used we can possibly held and provide more feedback.
It is worth noting that depending on internal anatomy to external anatomy you may in some cases have a difference in CBCT to XVI. With a difference so large I would put it down to the ROI initially. Also, is the difference when the Gantry is at 0, or are any of the Cameras blocked?
