Hadamard slice encoding for reduced-FOV diffusion-weighted imaging
(John Wiley & Sons, 2014)
Methods: A 2D echo-planar RF pulse and matching multiband refocusing RF pulses were designed using the Shinnar-Le Roux algorithm to reduce band interference, and variable-rate selective excitation to shorten the pulse ...
Huber function based reconstruction in accelerated phase-cycled bSSFP acquisitions for increased detection performance
(IEEE, 2017)
Balanced steady-state free precession imaging suffers from irrecoverable signal losses, called banding artifacts. A common way to alleviate banding artifacts without sacrificing scan-efficiency is to use multiple-acquisition ...
Category-selective top-down modulation in the fusiform face area of the human brain during visual search
(IEEE, 2017)
Several regions in the ventral-temporal cortex of the human brain are thought to have representations of specific categories of objects. Furthermore, a distributed network of frontal and parietal brain regions is implicated ...
Semantic similarity between Turkish and European languages using word embeddings
(IEEE, 2017)
Representation of words coming from vocabulary of a language as real vectors in a high dimensional space is called as word embeddings. Word embeddings are proven to be successful in modelling semantic relations between ...
Measuring cross-lingual semantic similarity across European languages
(IEEE, 2017)
This paper studies cross-lingual semantic similarity (CLSS) between five European languages (i.e. English, French, German, Spanish and Italian) via unsupervised word embeddings from a cross-lingual lexicon. The vocabulary ...
Phase-sensitive reconstruction for fat-water separation in multi-coil acquisitions
(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 ...
Functional subdomains within scene-selective cortex: parahippocampal place area, retrosplenial complex, and occipital place area
(Society for Neuroscience, 2016)
Functional MRI studies suggest that at least three brain regions in human visual cortex-the parahippocampal place area (PPA), retrosplenial complex (RSC), and occipital place area (OPA; often called the transverse occipital ...
Profile-encoding reconstruction for multiple-acquisition balanced steady-state free precession imaging
(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 ...
Comparison of system-matrix-based and projection-based reconstructions for field free line magnetic particle imaging
(Infinite Science Publishing, 2017)
In magnetic particle imaging (MPI), system sensitivity can be enhanced by scanning the sample along a field free line
(FFL) instead of a field free point (FFP). FFL MPI data can then be processed via system-matrix or ...
Phase-correcting non-local means filtering for diffusion-weighted imaging of the spinal cord
(John Wiley, 2018)
Purpose: DWI suffers from low SNR when compared to anatomical MRI. To maintain reasonable SNR at relatively high spatial resolution, multiple acquisitions must be averaged. However, subject motion or involuntary physiological ...
