Beam-modifying devices for ultra-high dose rate radiation therapy

Abstract

A beam-modifying assembly for an ultra-high dose rate (UHDR) electron linear accelerator that generally includes a beam modifier formed of a first material that defines a first layer and a second material that defines a second layer, the second material being different from the first material, wherein the first layer is provided on top of the second layer such that a first surface of the beam modifier comprises the first material and a second surface of the beam modifier comprises the second material, the second surface being on an opposite side of the beam modifier from the first surface; and a mounting assembly configured to retain the beam modifier, wherein the mounting assembly is adapted to be installed at an exit window of the linear accelerator such that the beam modifier is positioned at the exit window of the linear accelerator, wherein the first surface of the beam modifier faces the exit window and the second surface faces a subject to be irradiated.
