Laleh Golestanirad, University of Toronto Bio: Dr Laleh Golestanirad obtained her PhD in computational electromagnetics from Laboratory of Electromagnetics and Acoustics (LEMA), EPFL in 2011. She then joined the Department of Medical Biophysics at University of Toronto as a post-doctoral fellow, where she has worked on electromagnetic modeling and safety assessment of magnetic resonance imaging (MRI) of cardiovascular patients and transcranial magnetic stimulation (TMS) of human brain. She also has extensive expertise in functional MRI of brain tumour patients as a part of their pre-surgical brain mapping. Dr Golestanirad holds two fellowships from Swiss National Science Foundation and a US patent for neuro-stimulator electrodes. |

In this presentation Dr Laleh Golestanirad will talk about applications of computational electromagnetics in safety assessment of three medical procedures: transcranial magnetic stimulation (TMS), cardiovascular magnetic resonance imaging, and functional brain imaging.
TMS is a newly developed non-invasive brain stimulation technique that uses intensive magnetic pulses to induce electric currents in specific cortical regions to excite neural pathways. Dr Golestanirad presents her work on theoretical assessment of safety considerations encountered in the simultaneous application of TMS and neurological interventions with implanted metallic electrodes, such as electrocorticography. Metal implants are subject to magnetic forces due to fast alternating magnetic fields produced by the TMS coil. The question of whether or not the mechanical movement of the implants leads to irreversible damage of brain tissue is addressed by a comprehensive electromagnetic simulation followed by a careful mechanical analysis of brain tissue behaviour for damage assessment.
Dr Golestanirad will also present her work on safety assessment of MRI in patients with artificial heart valves. She outlines the procedure of developing a rigorous computational model based on a full-wave time-domain analysis of Maxwell’s equations, which quantifies the magnitude of resistive forces and torques applied on a variety of heart valves during MRI.
Finally, she will talk about applications of functional brain imaging and the role of electromagnetic modelling in developing parallel-transmit technology for the safe functional MRI of patients with deep brain stimulation electrodes.
