Fast Variance Prediction for Iteratively Reconstructed CT Images with Locally Quadratic Regularization
Predicting noise properties of iteratively reconstructed CT images is useful for analyzing reconstruction methods; for example, local noise power spectrum (NPS) predictions may be used to quantify the detectability of an image feature, to design regularization methods, or to determine dynamic tube c...
