# SZCH-X-Rays

**SZCH-X-Rays** comprises 741 pairs of posterior-anterior CXR and DES soft tissue images, acquired using a GE Discovery XR656 system in collaboration with our partner hospital. Initially stored in 14-bit DICOM format, the images were converted to PNG format to streamline the processing workflow, which feature an original resolution of $2021 \times 2021$ with a pixel size of 0.194 mm. Consistent with prior studies, examinations affected by operational errors, pronounced motion artifacts, severe pleural effusion, or pneumothorax were excluded because these conditions may substantially degrade the quality of DES soft tissue references. Finally, the dataset was partitioned into 592 training, 74 validation and 75 test pairs. The dataset is publicly available under the Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0) license. The test set of SZCH-X-Rays has been released [here](https://huggingface.co/datasets/diaoquesang/SZCH-X-Rays/resolve/main/SZCH-X-Rays_testset.zip). The training and validation sets, will be fully released immediately after the paper is officially accepted for publication.
