US 2026/0301282 A1 · METHOD FOR GENERATING RESOLUTION-ENHANCED MEDICAL IMAGING DATA, AND DEVICE

Abstract

A method and device for generating resolution-enhanced imaging data, are described. The method includes acquiring a raw three-dimensional projection generated by an imaging system scanning a subject, decomposing the raw three-dimensional projection dataset into a set of sub-datasets including different frequency information, executing texture orientation feature extraction on each sub-dataset in the set of sub-datasets to generate a set of texture orientation feature maps for each sub-dataset, inputting each sub-dataset and the set of texture orientation feature maps into a resolution enhancement neural network to generate a resolution-enhanced sub-dataset of each sub-dataset, wherein the resolution-enhanced sub-dataset has a higher resolution than the corresponding sub-dataset, and synthesizing the resolution-enhanced sub-datasets of all sub-datasets to generate a resolution-enhanced three-dimensional projection dataset corresponding to the raw three-dimensional projection dataset, wherein the resolution-enhanced three-dimensional projection dataset has a higher resolution and is used to reconstruct an image of the subject.
