New framework analyzes CT reconstruction, noise impacts strategy

Researchers have developed a unified framework to analyze design choices in self-supervised sparse-view CT reconstruction. Their experiments on simulated and real-world datasets indicate that the optimal partitioning strategy is highly dependent on the structure of measurement noise. Lattice-based splitting performs well with independent noise, while angular masking is more effective with correlated noise and actual measured data. The study also found that multi-partition splitting consistently enhances performance over projection-wise splitting in various scenarios. AI
