FD-Net: An Unsupervised Deep Forward-Distortion Model for Susceptibility Artifact Correction in EPI

2 code implementations • 18 Mar 2023 • Abdallah Zaid Alkilani, Tolga Çukur, Emine Ulku Saritas

Unlike previous methods, FD-Net enforces the forward-distortions of the correct image in both PE directions to be consistent with the acquired reversed-PE image pair.

Rapid TAURUS for Relaxation-Based Color Magnetic Particle Imaging

no code implementations • 9 Dec 2021 • M. Tunç Arslan, A. Alper Özaslan, Semih Kurt, Yavuz Muslu, Emine Ulku Saritas

An alternative calibration-free x-space-based method called TAURUS estimates a map of the relaxation time constant, by recovering the underlying mirror symmetry in the MPI signal.

Vicinity Effects of Field Free Point on the Relaxation Behavior of MNPs

no code implementations • 30 Nov 2021 • Atakan Topcu, Asli Alpman, Mustafa Utkur, Emine Ulku Saritas

In this work, we investigate the effects of the DC field on the relaxation behavior of the MNPs, with the goal of understanding the differences between the measured relaxations in Magnetic Particle Spectrometer (MPS) setups vs. MPI scanners.
