ARTIFICIAL INTELLIGENCE-BASED DEVICES AND METHODS FOR GEOMETRIC ALIGNMENT AND PREPROCESSING OF RAW CT IMAGES

The present disclosure relates to artificial intelligence-based devices and methods for geometric alignment and preprocessing of raw CT images. According to the present disclosure, when sensitive to a local error according to each characteristic, only linear transformation is applied to use the centrally aligned rigid registration result, and when the region of interest between patients is spatially matched or monitoring is required, a non-rigid registration result may be used.
