Contrast-Optimized Basis Functions for Self-Navigated Motion Correction in Quantitative MRI
Elisa Marchetto, Sebastian Flassbeck, Andrew Mao +1
Purpose: The long scan times of quantitative MRI techniques make motion artifacts more likely. For MR-Fingerprinting-like approaches, this problem can be addressed with self-naviga…

Rational Approximation of Golden Angles: Accelerated Reconstructions for Radial MRI
Nick Scholand, Philip Schaten, Christina Graf +6
Purpose: To develop a generic radial sampling scheme that combines the advantages of golden ratio sampling with simplicity of equidistant angular patterns. The irrational angle bet…

Bias-Reduced Neural Networks for Parameter Estimation in Quantitative MRI
Andrew Mao, Sebastian Flassbeck, Jakob Assländer
Purpose: To develop neural network (NN)-based quantitative MRI parameter estimators with minimal bias and a variance close to the Cramér-Rao bound. Theory and Methods: We generaliz…
