Description

This work investigates an improved quantification algorithm for CEST spectra using a joint Frobenuis Total Generalized Variation (TGV) regularization. The performance is assessed with simulations, phantom and in-vivo measurement with respect to systematic errors and robustness. For comparison a pixel-wise fit using the Levenberg-Marquardt algorithm and the IDEAL algorithm were implemented. The TGV algorithm show the best performance in parameter fitting stability and parameter map SNR.
