Section: claims

1. A method for virtual wedge treatment with portal imaging during radiation treatment by a radiation-emitting device, the method comprising: utilizing an image dose with a static jaw gap position to initiate a virtual wedge treatment with portal imaging;  continuing with the virtual wedge treatment from a reduced jaw gap position with a dynamic dose and dynamic jaw positioning; and  completing the virtual wedge treatment with a static dose in the static jaw gap position.  initiating the virtual wedge treatment with a dynamic jaw in a static jaw gap position;  providing an image dose to take a portal image;  adjusting a patient position based on the portal image;  moving the dynamic jaw to an initial jaw gap position;  providing a dynamic dose while moving the dynamic jaw from the initial jaw gap position to the static jaw gap position; and  providing a static dose in the static jaw gap position to complete the virtual wedge treatment. 2. The method of claim 1 wherein the static jaw gap position comprises a widest gap position necessary for the virtual wedge treatment. 3. The method of claim 1 further comprising repositioning a patient based on the portal imaging before the step of continuing with the virtual wedge treatment. 4. The method of claim 1 wherein the step of continuing further comprises moving a dynamic jaw to the reduced jaw gap position. 5. The method of claim 1 wherein the image dose, the dynamic dose, and the static dose comprise a total dose desired for the virtual wedge treatment. 6. The method of claim 1 wherein dynamic jaw positioning further comprises moving a dynamic jaw from the reduced jaw gap position to the static jaw gap position. 7. A method for virtual wedge treatment that includes portal imaging for improved radiation therapy, the method comprising: 8. The method of claim 7 wherein the image dose depends on a portal imaging device used to take the portal image. 9. The method of claim 7 further comprising determining a total dose in the static jaw gap position. 10. The method of claim 9 wherein the total dose comprises the image dose and the static dose. 11. The method of claim 10 wherein the total dose and the dynamic dose comprise a desired treatment dose for the virtual wedge treatment.
