Abstract: A method for simulating a particle transport may include recording transport paths of inputted particles and determining an uncertainty of each of lattice cells based on the transport paths of each batch of the inputted particles, a lattice cell being a qualified lattice cell if an uncertainty of the lattice cell does not exceed a first threshold; determining a standard-reaching rate of lattice cells in a region of interest (ROI), the ROI including at least one lattice cell, the standard-reaching rate of lattice cells in the ROI being equal to a ratio of the number of qualified lattice cells to a total number of lattice cells in the ROI; and if the standard-reaching rate of lattice cells in the ROI exceeds a second threshold, stopping inputting particles, and outputting the transport paths of the inputted particles.

Abstract: A method for quality assurance may include obtaining a state of a medical device. The method may also include obtaining a target plan of a target subject. The method may also include determining a prediction result based on the state of the medical device and the target plan of the target subject. The method may also include determining whether a quality assurance test passes based on the prediction result.
