Abstract:
1. A method comprising: receiving a first instruction to enter an imaging mode; in response to the first instruction, automatically reducing a focal spot size of a radiation beam, moving a flattening filter out of a path of the radiation beam, moving a first target for photon emission out of the path of the radiation beam and moving a second target for photon emission into the path of the radiation beam, and moving a scatter-reducing filter into the path of the radiation beam; receiving a second instruction to enter a first radiation treatment mode; and in response to the second instruction, automatically increasing a focal spot size of the radiation beam, moving the flattening filter into the path of the radiation beam, moving the second target out of the path of the radiation beam and moving the first target into the path of the radiation beam, and moving the scatter-reducing filter out of the path of the radiation beam.
