Detection of phase‐binning and interpolation artifacts in 4‐dimensional computed tomography imaging using deep learning and rule‐based approaches

We demonstrate state-of-the-art artifact detection accuracy using 3D deep learning models trained on synthetic data and a rule-based approach configured on true data, providing interpretability by highlighting which voxel locations indicate a slice is artifact-affected. The SwinUNETR model accuracy and fast run-time have the potential to enable more targeted artifact correction methods or signal an imaging technologist when to re-scan a patient in real-time.
