  • Patent number: 11857805
    Abstract: Systems and methods provide a radiotherapy treatment by focusing an electron beam on an x-ray target (e.g., a tungsten plate) to produce a high-yield x-ray output with improved field shaping. A modified electron beam spatial distribution is employed to scan the x-ray target, such as a 2D periodic beam path, which advantageously lowers the temperature of the x-ray target compared to typical compact beam spatial distribution. As a result, the x-ray target can produce a high yield x-ray output without sacrificing the life span of the x-ray target. The use of a 2D periodic beam path allows a much colder x-ray target functioning regime such that more dosage can be applied in a short period of time compared to existing techniques.
