Extraction of Multiple Sclerosis Lesions in MR Images Based on Active Contours

Işıkçı, Elif; Duru, Dilek Göksel (IEEE, 2015)

In this study, a semi automatic segmentation of multiple sclerosis lesions in magnetic resonance (MR) images based on active contours is done. Based on the seed area selection by the user, the parametric active contours ...

Investigation of Luminance Effect on the Emotional Assessment Using Hjorth Descriptors

Eroğlu, Kübra; Kurt, Pınar; Kayıkcıoğlu, Temel; Osman, Onur (IEEE, 2015)

The aim of this study is to investigate the impact of luminance level on the emotional evaluation from electroencephalography (EEG) records. EEG recordings obtained from 31 healty partipicants were used in this study. ...

Design and Implementation of Brain Computer Interface Based on Wireless EEG Measurements: A Pilot Study

Ilgin, Sena; Duru, Dilek Goksel (IEEE, 2015)

Brain computer interface (BCI), is a direct communication pathway between brain signals and an external device which often serves to support cognitive and emotional motor functions. The implementation and design of a human ...

Automated Segmentation of the Injured Liver

Palabaş, Tuğba; Osman, Onur; Ergin, Tuncer; Teomete, Uygar; Dandin, Özgür (IEEE, 2015)

A new method is developed about segmentation in patients with liver trauma due to traffic accidents and military injuries. It is seemed that normal or liver surger cases are used in most of the studies in the literature. ...

Solving asymmetric traveling salesman problem using genetic algorithm

Birtane Akar, Sibel; Şahingöz, O.K. (Institute of Electrical and Electronics Engineers Inc., 2015)

This study describes the genetic algorithm method that is most commonly used in search and optimization studies with solution approach of the asymmetric travelling salesman problem, which is the leading problem of the ...

Yolak Tabanlı Uzaysal İstatistik ile Talamik İnme Sonrası Anatomik Bağlantısallık Değişimlerinin İncelenmesi

Duru, Dilek Göksel; Yumerhodzha, Sami; Duru, Adil Deniz; Sencer, Serra; Bebek, Nerses (IEEE, 2015)

Diffusion tensor imaging (DTI) techniques allow the detection of changes in the microstructure of the human brain. The detection and follow-up of the underlying pathology and disruption of tissues is of vital importance. ...

Determining the Effect of Luminance on the EEG Measurement with STFT Method

Eroğlu, Kübra; Kurt, Pınar; Kayıkcıoğlu, Temel; Osman, Onur (IEEE, 2015)

The aim of this study is to observe the impact on the emotional evaluation of luminance, which is a perceptual feature of visual stimuli from electroencefelography (EEG) data recorded. EEG recordings obtained from 13 healthy ...

Semi-automated measurement of intraabdominal periorgan hematoma with a new method in patients with blunt abdominal trauma

Ergin, Tuncer; Dandin, Ozgur; Osman, Onur; Tulum, Gokalp; Teomete, Uygar; Cuce, Ferhat (IEEE, 2015)

Our aim is to demonstrate a new semi-automated method for measuring periorgan hematoma due to abdominal organ trauma. The new methods' performance was evaluated on randomly selected 31 CT scans from 31 patients (10 females, ...

Application of Telemedicine for Detection of Traumatic Spleen Injury

Özkan, Haydar; Ergin, Tuncer; Osman, Onur; Dandin, Özgür; Teomete, Uygar; Tulum, Gökalp (IEEE, 2015)

Using communication technologies, faster and better diagnosis and treatment methods of medical care are improved. Faster communications between doctors and patients are provided due to the improving technologies named ...

Determining Phase Duration of Scanning EMG Signals

Artuğ, Tuğrul; Osman, Onur; Göker, İmran; Baslo, Barış; Bolat, Bülent (IEEE, 2015)

There are more than one motor unit activities recorded simultaneously during scanning EMG recordings. It is not possible to determine the phase duration correctly by inspecting only one sweep. The other motor unit activities, ...
