Dose analysis radiotherapy systems and methods for determine delivered radiotherapy dose, dose rate, irradiation time and position information and planned radiotherapy dose, dose rate, irradiation time and position information. The dose analysis systems and methods further compare the as delivered dose, dose rate, irradiation time and position information to the planned dose, dose rate, irradiation time and position information to generate a graphical representation of one or more of the delivered dose, dose rate, irradiation time and position information versus planned dose, dose rate, irradiation time and position information.

Radiotherapy dose analysis methods and systems

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.).
