Analytic expressions for the ultimate intrinsic signal-to-noise ratio and ultimate intrinsic specific absorption rate in MRI
Kopanoglu, E.; Erturk, V. B.; Atalar, Ergin (Wiley, 2011-03-09)The ultimate intrinsic signal-to-noise ratio is the highest possible signal-to-noise ratio, and the ultimate intrinsic specific absorption rate provides the lowest limit of the specific absorption rate for a given flip ... -
A simple analytical expression for the gradient induced potential on active implants during MRI
Turk, E.A.; Kopanoglu, E.; Guney, S.; Bugdayci, K.E.; Ider, Y. Z.; Erturk, V. B.; Atalar, Ergin (2012)During magnetic resonance imaging, there is an interaction between the time-varying magnetic fields and the active implantable medical devices (AIMD). In this study, in order to express the nature of this interaction, ... -
Specific absorption rate reduction using nonlinear gradient fields
Kopanoglu, E.; Yilmaz, U.; Gokhalk, Y.; Atalar, Ergin (Wiley, 2013)The specific absorption rate is used as one of the main safety parameters in magnetic resonance imaging. The performance of imaging sequences is frequently hampered by the limitations imposed on the specific absorption ...
