1. 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, the density distribution in the subject being configured to be used to characterize densities of different portions of the subject;
generating, based on the radiotherapy treatment plan of the subject, a first equivalent count of simulation radiation particles, the simulation radiation particles being configured to be used to simulate a first dose distribution corresponding to the radiotherapy treatment plan of the subject;
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.
