[Legacy Report] IEEE AP/MTT/EMC/ED TURKEY CHAPTER SEMINAR SERIES -- SEMINAR 14
Speaker: Asst. Prof. Emine Ülkü Sarıtaş, Bilkent University
Topic: "Magnetic Particle Imaging: Applications and Magnetic Field Safety Limits"
Location: Middle East Technical University, Ankara, Turkey
Abstract: Magnetic Particle Imaging (MPI) is a new biomedical imaging modality, first introduced in 2005. MPI uses the nonlinear magnetization response of superparamagnetic iron oxide (SPIO) tracers to image their spatial distribution. Because human tissue does not exhibit a similar response, it is completely transparent in MPI images. This desirable feature makes MPI a very high contrast tracer imaging modality. Since its first introduction, MPI has evolved rapidly in terms of both hardware development and image reconstruction schemes, and has found important applications such as angiography, stem cell imaging, and cancer imaging. The first part of this presentation will introduce the imaging principles of MPI and its potential applications, in the light of our MPI efforts in National Magnetic Resonance Research Center (UMRAM) of Bilkent University.
MPI utilizes low-range RF frequencies (e.g., 10-150 kHz) for imaging. The magnetic field amplitudes, and thereby the imaging speed, are restricted by human peripheral nerve stimulation (PNS) thresholds. The second part of this talk will focus on these safety concerns and will present the results of our extensive human-subject experiments.
Bio: Dr. Saritas graduated with B.S. degree in Electrical and Electronics Engineering from Bilkent University in 2002. She was awarded the Lucent Technologies Stanford Graduate Fellowship for her graduate studies at Stanford University, at the Department of Electrical Engineering. There, she received her M.S. and Ph.D. degrees in 2004 and 2009, respectively. She then joined the Department of Bioengineering at University of California Berkeley, as a Siebel Stem Cell Institute Postdoctoral Fellow. Dr. Saritas has joined Bilkent University in September 2013. She is the recipient of the 2015 “Young Scientist Outstanding Achievement Award” (GEBIP) given by the Turkish Academy of Sciences (TÜBA), the 2016 “Young Scientist Award” (BAGEP) given by the Science Academy (Bilim Akademisi). Dr. Saritas is currently serving as an Associate Editor for IEEE Transactions on Medical Imaging, and as an Editorial Board Member for Nature Scientific Reports.
