Abstract
Methods, devices, and systems for processing ray data are provided. The methods include: smoothing initial ray data based on collection of a detector of a CT device through at least two time windows to obtain smoothed ray data corresponding to each time window having a different window length, the initial ray data including attenuation values of rays passing through an object to be examined and being obtained at a sampling frequency within a specified time period, determining initial fluctuating data based on the initial ray data and smoothed ray data corresponding to one of the time windows, the initial fluctuating data being associated with a fluctuation due to occlusion of the rays by a collimator of the CT device, and removing the fluctuation from the initial ray data to obtain target ray data based on the smoothed ray data corresponding to each time window and the initial fluctuating data.
