Abstract

The invention relates to a data correction method and device, computer equipment, a storage medium and a program product. The method comprises the following steps: acquiring a three-dimensional coordinate of a detector pixel unit, and calculating cosine correction data according to the three-dimensional coordinate of the detector pixel unit and a focus coordinate of a ray emission device; determining to-be-corrected response data of the detector, and correcting the to-be-corrected response data by using the cosine correction data to obtain target data; and determining a correction coefficient corresponding to the detector pixel unit according to the target data, and correcting the response data of the to-be-detected object according to the correction coefficient. By adopting the method, the effect of correcting the response non-uniformity of the pixel units of the detector can be improved.

Description

technical field [0001] The present application relates to the technical field of medical data processing, in particular to a data correction method, device, computer equipment, storage medium and computer program product. Background technique [0002] Computed Tomography (CT) equipment is an image detection equipment commonly used in scientific research institutions or hospitals. With the development of science and technology, photon counting detectors are gradually widely used in CT equipment. However, photon-counting detectors suffer from non-uniform response across pixels, which can lead to artifacts in the reconstructed image. [0003] In the traditional technology, the response data of the detector pixel unit is corrected by adopting a flat field correction (Flat Field Correction) method, so as to improve the response uniformity of the detector pixel unit, thereby eliminating artifacts in the reconstructed image. However, flat-field correction is less effective in impr...
