Title
Deep Learning Reconstruction of Chest CT Volumes from Single or Multi View Chest Radiographs
Summary
We want to explore possibilities of deep learning in the effective reconstruction of three-dimensional CT volumes from both single and multiple chest radiographs measured at varying projection angles. We intend to train two models with custom architectures: a 2D-to-3D encoder-decoder feature representation network and a generative adversarial network (GAN). We intend to use the NLST CT volumes to generate synthetic x-rays to create the training and validation datasets for these deep learning models.
Aims

- Use NLST CT volumes to generate synthetic chest radiographs at varying projection angles to create a training/validation dataset
- Use the training CT/x-ray data to train deep learning models for patient-specific chest CT reconstruction from single or multiple x-ray projections
- Compare generated CT volumes to actual NLST volumes to determine accuracies of developed models
