Publication number: 20200129782Abstract: A method of optimizing a radiation treatment plan of ion treatment, in which the optimization procedure is interrupted, some but not all low-weight spots are discarded and the optimization procedure is resumed with a reduced set of spots. The weight of one or more remaining spots may be increased before resuming the optimization procedure, for example by adding the spot weight of one or more of the discarded spots to one or more of the remaining spots.Type: ApplicationFiled: October 30, 2019Publication date: April 30, 2020Applicant: RaySearch Laboratories ABInventors: Oscar STÅL, Erik ENGWALL, Martin JANSON, Lars GLIMELIUS, Erik TRANEUS, Kjell ERIKSSON

Publication number: 20180289980Abstract: An optimization method for a radiotherapy plan using robust optimization to handle different scenarios that may occur during one treatment session because of patient movement. The optimization is based on the period and amplitude of the movement, the starting point of the treatment session within a period and the delivery time structure.Type: ApplicationFiled: April 11, 2016Publication date: October 11, 2018Applicant: RaySearch Laboratories ABInventors: Albin FREDRIKSSON, Erik ENGWALL
