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.

Abstract: Provided are a trajectory prediction method, an electronic device, and a storage medium. The method including that: a motion intention of an object is determined according to time-series location information and time-series posture information of the object, where the time-series location information is position information of the object at different time points within a preset time period, and the time-series posture information is posture information of the object at different time points within the preset time period, where the posture information at different time points includes orientation information of multiple parts of the object at the different time points; and a future trajectory of the object is determined according to the time-series location information, the time-series posture information and the motion intention.
