摘要： Some embodiments include reception of a first instruction to enter an imaging mode, and, in response to the first instruction, automatic performance of at least one of: reduction of a focal spot size of a radiation beam, movement of a flattening filter out of a path of the radiation beam, replacement of a first target for photon emission with a second target for photon emission, or movement of a scatter-reducing filter into the path of the radiation beam. Embodiments may further include reception of a second instruction to enter a first radiation treatment mode, and, in response to the second instruction, automatic performance at least one of: increase of a focal spot size of the radiation beam, movement of the flattening filter into the path of the radiation beam, replacement of the second target with the first target, or movement of the scatter-reducing filter out of the path of the radiation beam.
