How to cut ultrasound image from interface

Hi,
I’m using volume reconstruction module, but the user interface is being reconstructed too, I want to only use the ultrasound image in itself, I’ve tried using ClipRectangleOrigin = "200 206" ClipRectangleSize = "532 420" in the config file but it does not change anything.

I’m using Ascension Trackstar, Siemens P300 ultrasound, and the Epiphan frame grabber VGA2USB
