Nonlinear multiscale regularisation in MR elastography: Towards fine feature mapping.
Medical Image Analysis(2017)
摘要
•New Magnetic Resonance Elastography (MRE) software pipeline incorporating wavelet-based denoising and feature-detection techniques.•Systematic noise testing with new Finite Element Method (FEM)–based simulations.•Results robust to noise and show new levels of detail for MRE elastograms.
