Radiation therapy machine calibration apparatus providing multiple angle measurements |
摘要 |
A phantom for rotational radiation therapy machines allows beam fluence and energy to be measured at a variety of beam angles without intervening adjustment of the phantom. The phantom in the preferred embodiment provides two half cylinders directed along the axis of rotation of the machine abutting about a common center.
