Abstract
The present invention relates to a system and method for calibrating a radiation therapy device, such as a collimator. A method for calibrating a collimator according to an embodiment of the present invention is presented. The method comprises moving a leaf of a collimator; determining whether a distance between the leaf and a line approximately equals a predetermined measurement; and associating the predetermined measurement with a collimator specific count if the distance between the leaf and the line approximately equals the predetermined measurement.
