Synopsis

Keywords: Flow, System Imperfections: Measurement & Correction, Phase-Contrast, Eddy currentsWe propose a physics-driven approach for prediction of eddy current-induced background phase offsets in 2D PC-MRI. The method leverages the applied gradient waveforms and a circuit model to estimate the system-dependent parameters that govern the background phase. The aim is to use these parameters and the model to predict the background phase of clinical acquisitions from pulse sequence information only. Our method achieved an RMSE of 1.05 cm/s and adequate visual quality.
