Optimizing IVIM measurement on magnetic resonance linear accelerator using multi-b-value acquisition and physics-informed neural network.
BACKGROUND Accurate quantification of intravoxel incoherent motion (IVIM) parameters on the magnetic resonance linear accelerator (MR-Linac) is challenging due to low signal-to-noise ratio and time constraints. PURPOSE This study aimed to evaluate the impact of b-value acquisition strategies and estimation algorithms...
