  • System and a method for verifying a treatment plan
    Patent number: 10610703
    Abstract: The present invention relates to a method for determining an energy fluence correction in a quality assurance system for a radiation therapy apparatus, which method comprises receiving a treatment plan description; generating a set of measured phantom dose values; generating a set of determined phantom dose values, by determining phantom dose values based on at least the treatment plan description and a phantom description; determining a set of phantom dose corrections based on at least the set of determined phantom dose values and the set of measured phantom dose values; and determining an energy fluence correction based on at least the set of phantom dose corrections. It further relates to a method for determining a reconstructed patient dose distribution based on at least the energy fluence correction, a patient description, and further data related to the treatment plan description. It also relates to corresponding quality assurance and control systems.

  • A SYSTEM AND A METHOD FOR VERIFYING A TREATMENT PLAN
    Publication number: 20180200537
    Abstract: The present invention relates to a method for determining an energy fluence correction in a quality assurance system for a radiation therapy apparatus, which method comprises receiving a treatment plan description; generating a set of measured phantom dose values; generating a set of determined phantom dose values, by determining phantom dose values on basis of at least the treatment plan description and a phantom description; determining a set of phantom dose corrections on basis of at least the set of determined phantom dose values and the set of measured phantom dose values; and determining an energy fluence correction on basis of at least the set of phantom dose corrections. It further relates to a method for determining a reconstructed patient dose distribution on basis of at least the energy fluence correction, a patient description, and further data related to the treatment plan description. It also relates to corresponding quality assurance and control systems.
