A New Practical Intracerebral Hematoma Volume Calculation Method and Comparison to simple ABC/2
Cüce, Ferhat; Tulum, Gökalp; Dandin, Özgür; Ergin, Tuncer; Karadaş, Ömer; Osman, Onur (Turkish Neurosurgical Soc., 2020)AIM: To find a more practical and effective formula than simple ABC/2 (sABC/2) to calculate the hematoma volume in patients with subdural and parenchymal haemorrhage. MATERIAL and METHODS: We reviewed the records of 157 ... -
A novel method for pulmonary embolism detection in CTA images
Özkan, Haydar; Osman, Onur; Şahin, Sinan; Boz, Ali Fuat (Elsevier, 2014)In this paper, we propose a new computer-aided detection (CAD) – based method to detect pulmonary embolism (PE) in computed tomography angiography images (CTAI). Since lung vessel segmentation is the main objective to ... -
Observation of the Effect of the Increase in Luminance Level on Emotional Assessment in EEG Records Using Welch Method
Eroğlu, Kübra; Kurt, Pınar; Osman, Onur; Kayıkçıoğlu, Temel (IEEE, 2017)The aim of this study is to investigate the effect of the difference in level of luminance of visual stimuli on the emotional evaluation (negative, positive, neutral) from electroencephalogram (EEG) data recorded. EEG ... -
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, ... -
Spleen segmentation on CT using convolutional neural network
Tulum, Gokalp; Aydinli, Bulent; Osman, Onur; Yilmaz, Vural Taner; Ergin, Tuncer; Cuce, Ferhat; Dandin, Ozgur; Kisaoglu, Abdullah; Demiryilmaz, Ismail; Yaprak, Muhittin (Institute of Electrical and Electronics Engineers Inc., 2019)The automated segmentation systems have been evolving from experimental to clinical applications in radiology. By taking advantage of these, radiologists can increase diagnostic accuracy in their interpretations. In this ... -
Variable active antenna spatial modulation
Osman, Onur (INST ENGINEERING TECHNOLOGY-IET, 2015)In this study, variable active antenna spatial modulation (VASM) technique, which allows the selection of any number of antennas (but not a constant number of active antennas) to transmit a symbol at the same signalling ... -
Variable antenna-space shift keying for high spectral efficiency in exponentially correlated channels
Osman, Onur (Wiley, 2017)the case of correlated channels. Then, to reduce the correlation effect, a novel antenna codeword construction method that minimizes the pairwise error probability is introduced for exponentially correlated channels. ... -
Wigner Ville dağılımı yöntemi ile görüntülerdeki lüminans düzeyinin EEG kayıtlarındaki etkisinin incelenmesi
Eroğlu, Kübra; Kurt, Pınar; Kayıkçıoğlu, Temel; Osman, Onur (IEEE, 2016)Yapılan çalışmanın amacı duygusal değerlendirme ve lüminans arasındaki ilişkinin elektroensefalografi (EEG) kayıtlarında gözlemlenen P300 geç bileşeni üzerinden incelenmesidir. Çalışmada 13 sağlıklı gönüllüye ait EEG ... -
Yaralanmış karaciğer bölütlemesi için sağ batın bölge sınırının belirlenmesi
Palabaş, Tuğba; Osman, Onur; Ergin, Tuncer; Teomete, Uygar; Dandin, Özgür; Aydın, Nizamettin (IEEE, 2016)Acil servise getirilen travmalı hastalar için acil operasyon ihtiyacının otomatik belirlenmesi hasta yönetimine hız kazandırma açısından oldukça önemlidir. Bu çalışmada batın içi travmalar sonucunda hacmi ve lokasyonu ...
