Abstract
Systems and methods for determining a radiation isocenter of a linear accelerator (LINAC). Determining the radiation isocenter may include determining a set of three-dimensional (3D) radiation beam axes of the LINAC from two-dimensional (2D) radiation transmission images. The radiation isocenter may be determined based on at least the set of 3D radiation beam axes. Determining the set of 3D radiation beam axes may including constructing a 3D radiation beam axis based on a determined location of a beam axis of a radiation beam generated with a gantry of the LINAC at an angle relative to a reference gantry angle, a determined center of a shadow of a radiation opaque marker in the radiation field of the radiation beam, and the gantry angle.
