Fast system calibration with coded calibration scenes for magnetic particle imaging

İlbey, Serhat; Top, C. B.; Güngör, Alper; Çukur, Tolga; Sarıtaş, Emine Ülkü; Güven, H. Emre (IEEE, 2019)

Magnetic particle imaging (MPI) is a relatively new medical imaging modality, which detects the nonlinear response of magnetic nanoparticles (MNPs) that are exposed to external magnetic fields. The system matrix (SM) method ...

Pulse shape design using iterative projections

Güven, H. Emre; Çetin, A. Enis (IEEE, 2005-09)

In this paper, the pulse shape design for various communication systems including PAM, FSK, and PSK is considered. The pulse is designed by imposing constraints on the time and frequency domains constraints on the ...

Signal recovery from partial fractional fourier domain information and pulse shape design using iterative projections

Güven, H. Emre (Bilkent University, 2005)

Signal design and recovery problems come up in a wide variety of applications in signal processing. In this thesis, we first investigate the problem of pulse shape design for use in communication settings with matched ...

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 ...
