PURPOSE Image-guided intensity-modulated radiotherapy can improve protection of organs at risk when large abdominal target volumes are irradiated. We estimated the daily positioning accuracy of ultrasound-based image guidance for abdominal target volumes by a direct comparison of daily imaging obtained with cone beam computed tomography (CBCT). METHODS AND MATERIALS Daily positioning (n = 83 positionings) of 15 patients was completed by using ultrasound guidance after an initial CBCT was… CONTINUE READING
