Accelerated phase-cycled SSFP imaging with compressed sensing

Çukur, T. (Institute of Electrical and Electronics Engineers Inc., 2015)

Balanced steady-state free precession (SSFP) imaging suffers from irrecoverable signal losses, known as banding artifacts, in regions of large B0 field inhomogeneity. A common solution is to acquire multiple phase-cycled ...
Rapid reconstruction for parallel magnetic resonance imaging with non-Cartesian variable-density sampling trajectories

Şenel, Celal Furkan (Bilkent University, 2020-01)

Due to long acquisition times, the use of magnetic resonance imaging (MRI) remains challenging in some applications. Variable-density acquisitions enable scan acceleration while maintaining a desirable trade-oﬀ between ...
Statistically segregated k-space sampling for accelerating multiple-acquisition MRI

Şenel, L. Kerem; Kılıç, Toygan; Güngör, Alper; Kopanoğlu, Emre; Güven, H. Emre; Sarıtaş, Emine U.; Koç, Aykut; Çukur, Tolga (IEEE, 2019)

A central limitation of multiple-acquisition magnetic resonance imaging (MRI) is the degradation in scan efficiency as the number of distinct datasets grows. Sparse recovery techniques can alleviate this limitation via ...
