摘要： The present disclosure relates to a data processing method and device. The data processing method comprises steps of: performing detector response calibration based on a detector response obtained by an incidence of rays with known energy into a detector to obtain a detector response model; obtaining a photon counting model of the detector between incident energy spectrum data of the detector and detected energy spectrum data of the detector based on the detector response model; and performing a deconvolution operation on counts of photons in respective energy regions in the detected energy spectrum data of the detector based on the photon counting model of the detector, to obtain real counts of photons in respective energy regions in the incident energy spectrum data of the detector.

摘要： A method of acquiring feature information of a detected object is provided, including: controlling the detected object to pass through a detection apparatus; controlling an imaging system to perform radiation scanning on the detected object acquiring a radiation scanning image of the detected object acquiring feature information of the detected object through the radiation scanning image. The detected object includes a first part, a detection part and a second part sequentially in a first direction. The acquiring feature information of the detected object through the radiation scanning image includes: acquiring a first boundary line between the detection part and the first part and a second boundary line between the detection part and the second part through the radiation scanning image; and calculating a dimension between the first boundary line and the second boundary line in the first direction to acquire a dimension of the detection part in the first direction.
