Abstract:
A method and apparatus for precisely reproducing the position of a vaginal cylinder in relation to a patient to ensure that a planned radiation dose can be delivered with high precision to the intended treatment target volumes. Treatment delivery is carried out by using an image-guided system to locate the position of the vaginal cylinder and comparing it to the coordinate of the vaginal cylinder obtained in the treatment plan. The displacement in the position of the vaginal cylinder from the treatment plan is corrected by calculating the transformation matrix and entering the resulting value into a position adjusting assembly which is attached to vaginal cylinder. The position adjusting assembly adjusts the vaginal cylinder to exactly reproduce its location relative to the patient's anatomy, eliminating geometric and dosimetric error.
