In this work, a methodology is developed to solve the forward problem of electromagnetic source imaging using realistic head models. For this purpose, first segmentation of the 3 dimensional MR head images is performed. Then triangular, quadratic meshes are formed for the interfaces of the tissues. Thus, realistic meshes, representing scalp, skull, CSF, brain and eye tissues, are formed. At least 2000 nodes for the scalp and 5000 for the cortex are needed to obtain reasonable geometrical approximation. Solution of the forward problem using our previous Boundary Element Method (BEM) formulation with quadratic elements remains to be made.

An accelerated BEM formulation for the forward problem solution of ESI using realistic head models Akalm, Z; Gençer, Nevzat Güneri (2003-09-21) In this study, the forward problem of electrical source imaging (ESI) is solved using the Boundary Element method (BEM) with realistic head models. The realistic model consists of scalp, skull, CSF, brain and eyes. To get more accurate results quadratic elements are used in the meshes-and a new method is proposed for the generation of the quadratic mesh. An accelerated method is proposed for the solution of the potential field.
A new boundary element method formulation for the forward problem solution of electro-magnetic source imaging Tanzer, IO; Gençer, Nevzat Güneri (1997-11-02) Numerical solution of the potential and magnetic fields far a given electrical source distribution in the human brain is the essential part of electro-magnetic source imaging. In this study, the performance of Boundary Element Method (BEM) with different surface element types is explored. A new BEM formulation is derived that makes use of isoparametric linear and quadratic elements. It is shown that, quadratic elements provides superior performance over linear elements in terms of computation time and accur...
Application of High Resolution Magnetic Resonance Imaging Methods for Spinal Cord Tissue Segmentation Durlu, Caglayan; Erdogan, Hasan Balkar; Kucukdeveci, Osman Fikret; Gençer, Nevzat Güneri (2016-01-01) This paper presents the primitive results of high resolution Magnetic Resonance (MR) Imaging experiments that are performed for spinal cord segmentation purposes. In the study, it is aimed to image the epidural space, the cerebrospinal fluid, the white matter and the gray matter tissues in the lower cervical and upper thoracic regions of the spine with a maximum voxel size of 1x1x1 mm(3). For this purpose, the MRI sequences providing T2 and T2* images and used for spinal cord segmentation in the literature ...
OPTIMIZATION OF ENCODING AND ERROR PROTECTION PARAMETERS FOR 3D VIDEO BROADCAST OVER DVB-H Aksay, Anil; Bugdayci, Done; Akar, Gözde (2011-05-18) In this study, we propose a heuristic methodology for modeling the end-to-end distortion characteristics of an error resilient broadcast system for 3D video overDigital Video Broadcasting -Handheld (DVB-H). We also use this model to optimally select the parameters of the video encoder and the error correction scheme, namely, Multi Protocol Encapsulation Forward Error Correction (MPE-FEC), minimizing the overall distortion. The proposed method models the RQ curve of video encoder and performance of channel c...
Development of D -type fiber optic sensors for detection of refractive index variation in evanescent wave field / Güleryüz, Burcu; Durucan, Caner; Aslan, Mustafa M.; Department of Metallurgical and Materials Engineering (2014) The purpose of this study is to design, construct, develop and test D-type multimode fiber optic (F/O) sensors based on evanescent wave field sensing. A comprehensive work has been performed both theoretically and experimentally using a geometrical modification approach to improve the sensors response in different manners for detecting the refractive index (RI) variations and bio-molecular interactions in aqueous environment. In this study, the D-type F/O sensors performance was improved utilizing optical w...
