Abstract
In patients from whom good sonographic image quality could be obtained, ultrasound improved daily positioning accuracy. In the case of satisfactory image quality, ultrasound guidance improved accuracy compared to that of skin marks only minimally. If sonographic image quality was unsatisfactory, daily CBCT scanning improved treatment accuracy distinctly over that of ultrasound. Use of daily ultrasound or CBCT imaging can help to reduce PTV margins and protect organs at risk compared to the use of skin mark-based positioning.
