Effects of auditory attention on language representation across the human brain

Yılmaz, Özgür (Bilkent University, 2019-09)

Humans can effortlessly identify target auditory objects during natural listening and shift their focus between different targets. Unique allocation of brain resources would be inefficient for semantic search task. Here, ...

Enhanced phase-sensitive SSFP reconstruction for fat-water separation in phased-array acquisitions

Yılmaz, Özgür; Sarıtaş, Emine Ülkü; Çukur, Tolga (John Wiley and Sons Inc., 2016)

Purpose: To propose and assess a method to improve the reliability of phase-sensitive fat–water separation for phased-array balanced steady-state free precession (bSSFP) acquisitions. Phase-sensitive steady-state free ...

Full‐brain coverage and high‐resolution imaging capabilities of passband b‐SSFP fMRI at 3T

Lee, J. H.; Dumoulin, S.; Sarıtaş, Emine Ülkü; Glover, G.; Wandell, B.; Nishimura, D.; Pauly, J. (Wiley‐Liss, Inc., 2008)

Passband balanced-steady-state free precession (b-SSFP)fMRI is a recently developed method that utilizes the passband(ﬂat portion) of the b-SSFP off-resonance response to measureMR signal changes elicited by changes in ...

Phase-sensitive reconstruction for fat-water separation in multi-coil acquisitions

Yılmaz, Özgür; Sarıtaş, Emine Ülkü; Çukur, Tolga (IEEE, 2016)

Phase-sensitive steady-state free precession (PS-SSFP) is an effective technique for separating fat and water tissues, based on the phase difference between balanced steady-state free precession (bSSFP) bands. However, in ...

Profile-encoding reconstruction for multiple-acquisition balanced steady-state free precession imaging

Ilicak, Efe; Senel, Lutfi Kerem; Biyik, Erdem; Çukur, Tolga (John Wiley and Sons Inc., 2017)

Purpose: The scan-efficiency in multiple-acquisition balanced steady-state free precession imaging can be maintained by accelerating and reconstructing each phase-cycled acquisition individually, but this strategy ignores ...

SSFP-based MR thermometry

Paliwal, V.; El-Sharkawy, A.-M.; Du, X.; Yang, X.; Atalar, Ergin (John Wiley & Sons, 2004)

Of the various techniques employed to quantify temperature changes by MR, proton resonance frequency (PRF) shift-based phase-difference imaging (PDI) is the most accurate and widely used. However, PDI is associated with ...
