A compensator for use in irradiating the whole brain with parellel opposed lateral fields was made from a stack of thin tempered aluminum plates. This configuration gives a wide latitude of degrees of compensation and can accommodate a broad range of head sizes. Dosimetry studies indicate that overcompensation may be desirable to reduce the dose to the mid-coronal plane of the skull and scalp without seriously affecting the dose uniformity in the treatment volume.
