Abstract
The present disclosure relates to systems and methods for reconstructing fluence map. The system may obtain a plurality of radiation tasks based on a radiotherapy plan. Each of the plurality of radiation tasks may include a radiation field corresponding to the radiation task. For each of the plurality of radiation tasks, the system may determine whether a shape change between a radiation field corresponding to the radiation task and a radiation field corresponding to a preceding radiation task exceeds a shape change threshold. The system may determine a fluence map corresponding to the radiation task based on a first determination result of whether the shape change between the radiation field corresponding to the radiation task and the radiation field corresponding to the preceding radiation task exceeds the shape change threshold.
