Analysis of current induction on thin conductors inside the body during MRI scan

Açıkel, Volkan (Bilkent University, 2014)

The aim of this thesis is to develop a method to analyze currents on thin conductor structures inside the body during Magnetic Resonance Imaging (MRI) scan based on Modified Transmission Line Method (MoTLiM). In this ...

Analysis of the electromagnetic field inside the gradient coils and investigation of the nerve and cardiac stimulation risk for the patients during MRI

Abacı, Esra (Bilkent University, 2008)

During magnetic resonance imaging (MRI), the static magnetic field, the radio frequency field and the gradient fields are utilized. In the literature, there are several studies with the aim of understanding the bioeffects ...
