Abstract
Method and system aspects for utilizing portal images in a virtual wedge treatment during radiation treatment by a radiation-emitting device are described. In a method aspect, and system for achieving same, the method includes utilizing an image dose with a static jaw gap position to initiate a virtual wedge treatment with portal imaging. The method further includes continuing with the virtual wedge treatment from a reduced jaw gap position with a dynamic dose and dynamic jaw positioning. In addition, the virtual wedge treatment in completed with a static dose in the static jaw gap position.
