Outline
Transformer Volumetric Super-Resolution Network (TVSRN-V2) is a Transformer-based super-resolution (SR) framework designed to enhance the resolution of low-dose chest CT. Built with scalable components including Through-Plane Attention Blocks (TAB) and Swin Transformer V2, it effectively reconstructs fine anatomical details from low-dose CT and integrates seamlessly with downstream analysis pipelines. Its performance is evaluated in various clinical cohorts for three clinical tasks: lung cancer lobe segmentation, radiomics genomics, and prognosis prediction, and a virtual low-resolution augmentation technique that does not require personal information is introduced to increase the robustness to various acquisition protocols.
