Abstract
A system for generating a dose distribution is provided. The system may obtain a first dose distribution in at least a portion of a subject. The system may also obtain a trained machine learning model. The system may further generate, based on the first dose distribution and the trained machine learning model, a second dose distribution in the at least a portion of the subject, wherein the second dose distribution has a higher accuracy than that of the first dose distribution.

1-20. (canceled)
A system, comprising:
- at least one storage device storing a set of instructions;
- and
- at least one processor in communication with the at least one storage device, when executing the stored set of instructions, the at least one processor causes the system to perform operations including:
- obtaining personalized data of a subject, the personalized data of the subject including a radiotherapy treatment plan of the subject and a density distribution in the subject;
- generating, based on the radiotherapy treatment plan of the subject, a first equivalent count of simulation radiation particles;
- simulating, based on the density distribution in the subject, transport of each of the simulation radiation particles;
- and
- determining, based on the transport of each of the at least a portion of the radiation particles, the first dose distribution in at least a portion of the subject.
