Abstract

We propose an end-to-end optimization approach to reduce T2 blurring in single-shot TSE sequences, by performing a joint optimization of Flip Angle Design and DenseNet parameters using he original transverse magnetization image at a certain TE as target. Our approach generalizes well to in vivo measurements at 3T, revealing enhanced white and grey matter contrast and fine structures in human brain.
