Fourier Decomposition-Based Phase Processing Technique: A Novel Approach for 1-D Phase Unwrapping
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingThe performance of coherence analysis system (CAS) is critically dependent on phase accuracy. Most advanced phase unwrapping (PU) algorithms are designed for 2-D problem, but data from various interferometric systems are typically acquired as 1-D time ...

Unwrapping phase contrast MRI by iterative graph cuts
Magnetic Resonance in Medicine, Volume 92, Issue 4, Page 1484-1495, October 2024.Abstract Purpose To develop and evaluate a phase unwrapping method for cine phase contrast MRI based on graph cuts. Methods A proposed Iterative Graph Cuts method was evaluated in 10 cardiac patients with two‐dimensional flow quantification which was repeated at low venc settings to provoke wrapping.

Combined MR quantitative susceptibility mapping and multi‐shell diffusion in Parkinson's disease
Journal of Neuroimaging, Volume 34, Issue 5, Page 603-611, September/October 2024.Abstract Background and Purpose Quantitative susceptibility mapping (QSM), neurite orientation dispersion and density imaging (NODDI), and the g‐ratio have separately shown differences between Parkinson's disease (PD) and healthy controls. The g‐ratio has, however, not been studied in PD in the substantia nigra (SN) and the putamen.

Auxetic Biomedical Metamaterials for Orthopedic Surgery Applications: A Comprehensive Review
Orthopaedic Surgery, Volume 16, Issue 8, Page 1801-1815, August 2024.Auxetic biomedical metamaterials for joint surgery, spinal surgery, trauma surgery, and sports medicine applications. Poisson's ratio in auxetic materials shifts from typically positive to negative, causing lateral expansion during axial tension. This scale‐independent characteristic, originating from tailored architectures, exhibits specific physical ...
