Title:
METHODS AND SYSTEMS FOR CORRECTING PROJECTION DATA
Document Type and Number:
WIPO Patent Application WO/2022/152218
Kind Code:
A1
Abstract:
Provides a method and system for correction projection data. The method includes: obtaining the entity projection data and the transformed projection data related to the imaging object, the transformed projection data includes the first projection data related to the pixel shading generated by the detector components; inputting the entity projection data, the transformed projection data to the trained correction model and obtaining the correction projection data. The correction model obtained through training realizes the efficient and accurate correction of multi-energy imaging/spectral radiography, so that the obtained correction projection data may be more in line with the complexity of the actual system, and the correction effect may be better.
