A new study by Zahide Pamir and Huseyin Boyacı has been published in Vision Research. In this study, it is shown that perceived contrast is affected by context-dependent lightness of equiluminant backgrounds. More specifically, when identical gratings are superimposed on equiluminant backgrounds, the one on the perceived-lighter background appeared to have higher contrast. Results showed that perceived contrast is not driven only by the localized features of a retinal image, instead visual system uses lightness information to determine perceived contrast.

UMRAM is partnering with ASELSAN to develop novel imaging technologies for Magnetic Particle Imaging (MPI), together with German partners University of Lübeck and Nano4Imaging. This Turkish-German 2+2 collaborative project was chosen as one of the 9 projects to be funded (out of 130 applications), after scientific evaluations by both countries. The 3-year project will be funded by TUBITAK on the Turkish side and by the Federal Ministry of Education and Research (BMBF) on the German side. The main goal of the project is to develop MPI as a rapid and safe interventional imaging technique. The principal investigator of the project at Bilkent is Asst. Prof. Emine Ulku Saritas. 

This project was recently publicized in the Turkish news agencies. See, for example, this link

Recently Demir Research Group has published a paper in ACS Applied Materials & Interfaces Journal. This study reports Mn−Fe heterodoped ZnSe tetrapod nanocrystals (NCs) synthesized to synergistically enhance contrast in both T1- and T2-weighted magnetic resonance imaging (MRI). The proposed NCs were prepared using a customized heteroarchitecture such that the manganese (Mn) is confined in the core and iron (Fe) in the branches of the tetrapods.

"Colloidal Nanoparticles as dual-modal contrast age for MRI" from Demir Research Group recently has been published in Nanoscale Journal. This work reports the first study of highly monodisperse and crystalline iron oxide nanocubes with sub-nm controlled size distribution (9.7 ± 0.5 nm in size) that achieve simultaneous contrast enhancement in both T1- and T2-weighted magnetic resonance imaging (MRI).

 

A new study by Özgür Yılmaz, Dr. Emine Ülkü Sarıtaş and Dr. Tolga Çukur has been published in JMRI. In this study, a new strategy is proposed for phase-sensitive fat-water separation in bSSFP images acquired with phased-array coils. In vivo results show that the proposed strategy outpetforms conventional methods in terms of fat-water separation. Click here for the full article.

 


A new study by Efe Ilıcak, Prof. Dr. Kader Karlı Oğuz and Dr. Tolga Çukur has been published in NMR in Biomedicine. The study develops a novel reconstruction technique for non-contrast enhanced angiograms for improved blood-background contrast without compromising vessel depiction. Simulations and in vivo experiments conducted during the study show that the developed strategy outperforms regular reconstructions consistently across subjects. Click here for the full article.

ISMRM'16 was held in Singapore. UMRAM had a strong appearance there.

Berk Silemek received magna cum laude merit award for his presentation entitled Subacute In-Vivo RF Heating of an Active Medical Implantable Device Under MRI Using Temperature Sensor Implant. 

Cemre Ariyurek's traditional poster was selected among the top ten most popular abstracts. Her poster is entitled "Experimental Validation of High Shear Wave Displacement at Mode Frequencies in MR Elastography".

Koray Ertan worked on the challenge on simultaneous multislice imaging and become 5th. ASELSAN researcher, Emre Kopanoglu become 6th on the same challenge. Emre Kopanoglu become 5th in the pTx challenge.

Congratulations to all.
