Publication number: 20230001233Abstract: Presented systems and methods enable efficient and effective robust radiation treatment planning and treatment, including analysis of dose rate robustness. In one embodiment, a method comprising accessing treatment plan information, accessing information corresponding to an uncertainty associated with implementation of the radiation treatment plan, and generating a histogram, wherein the histogram conveys a characteristic of the treatment plan including an impact of the uncertainty on the characteristic. The histogram can be a dose rate volume histogram and can be utilized to test a degree of robustness of a treatment plan (e.g., including allowance for uncertainty scenarios, etc.). The uncertainty can be associated with potential variation associated with tolerances (e.g., radiation system/machine performance tolerance, patient characteristic tolerances, etc.) and set up issues (e.g., variation in initial system/machine set up, variation patient setup/position, etc.Type: ApplicationFiled: June 30, 2021Publication date: January 5, 2023Inventors: Tina PFEILER, Reynald VANDERSTRAETEN, Michiko ROSSI, Isabel HUTH, Viljo PETAJA

Publication number: 20220176156Abstract: Treatment fields can be produced as part of a treatment plan that achieves a desired balance between field delivery time and dose based on machine parameters and knowledge, such as machine-specific beam production, transport and scanning logic, and/or a maximum treatment time value. The treatment parameters can be adjusted using a graphical user interface so that treatment time or dosimetry is prioritized. As a result, the overall treatment time is reduced, and hence treatment quality and patient experience are improved.Type: ApplicationFiled: December 29, 2020Publication date: June 9, 2022Inventors: Arturs MEIJERS, Perttu NIEMELA, Roni HYTONEN, Reynald VAN DER STRAETEN, Jan TIMMER, Timo KOPONEN, Christel SMITH, Isabel HUTH
