Title
X-ray Dissectography Improves Lung Nodule Detection
Summary
Although chest radiographs are the most frequently performed imaging tests worldwide due to their cost-effectiveness and widespread accessibility, the structural superposition along the x-ray paths often renders suspicious or concerning lung nodules inconspicuous and difficult to detect. In this study, we develop “X-ray dissectography” to dissect lungs digitally from a few radiographic projections, suppress the interference of irrelevant structures, and improve lung nodule detectability.
Aims

1. improve the image quality of X-ray image quality.
2. Improve the lung nodule detection performance.
