  • Patent number: 11471120
    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.

  • Patent number: 11073998
    Abstract: The present disclosure discloses a method, apparatus for processing a disk bad sector, and a computer storage medium. The method includes: obtaining a target disk that is to be processed, and detecting bad sector data in the target disk; combining bad sector areas represented by the bad sector data, to obtain a usable area different from the bad sector areas in the target disk; and determining, according to a detection result, whether the target disk is usable, reconstructing storage space of the target disk based on the usable area if the target disk is usable, and setting an access parameter for the reconstructed storage space. The technical solutions provided by the present disclosure can improve processing efficiency of a faulty disk while saving a disk resource.

  • Publication number: 20210224231
    Abstract: A file reading method includes: sending, by the application entity, a read request to a file system; when the application entity receives a first error response returned by the file system, determining, by the application entity, a file source of the target file and obtaining the target file from the file source; and sending, by the application entity, a write request to the file system, where the write request is used to instruct the file system to re-store the target file according to a replacement storage path.

  • Publication number: 20170150940
    Abstract: The present disclosure includes: in a collimation condition, performing air scan based on a predetermined reference scanning condition to obtain air calibration data corresponded to the predetermined reference scanning condition; and obtaining air calibration data of non-reference scanning conditions in the collimation condition based on the air calibration data corresponded to the predetermined reference scanning condition and stored incremental differences, wherein the stored incremental differences are differences between the air calibration data of the predetermined reference scanning condition and the non-reference scanning conditions.
