DESCRIPTION:Laleh Golestanirad\, University of Toronto\nBio: Dr Laleh Gole
 stanirad obtained her PhD in computational electromagnetics from Laborator
 y of Electromagnetics and Acoustics (LEMA)\, EPFL in 2011. She then joined
  the Department of Medical Biophysics at University of Toronto as a post-d
 octoral fellow\, where she has worked on electromagnetic modeling and safe
 ty assessment of magnetic resonance imaging (MRI) of cardiovascular patien
 ts and transcranial magnetic stimulation (TMS) of human brain. She also ha
 s extensive expertise in functional MRI of brain tumour patients as a part
  of their pre-surgical brain mapping.\nDr Golestanirad holds two fellowshi
 ps from Swiss National Science Foundation and a US patent for neuro-stimul
 ator electrodes.\nIn this presentation Dr Laleh Golestanirad will talk abo
 ut applications of computational electromagnetics in safety assessment of 
 three medical procedures: transcranial magnetic stimulation (TMS)\, cardio
 vascular magnetic resonance imaging\, and functional brain imaging.\nTMS i
 s a newly developed non-invasive brain stimulation technique that uses int
 ensive magnetic pulses to induce electric currents in specific cortical re
 gions to excite neural pathways. Dr Golestanirad presents her work on theo
 retical assessment of safety considerations encountered in the simultaneou
 s application of TMS and neurological interventions with implanted metalli
 c electrodes\, such as electrocorticography. Metal implants are subject to
  magnetic forces due to fast alternating magnetic fields produced by the T
 MS coil. The question of whether or not the mechanical movement of the imp
 lants leads to irreversible damage of brain tissue is addressed by a compr
 ehensive electromagnetic simulation followed by a careful mechanical analy
 sis of brain tissue behaviour for damage assessment.\nDr Golestanirad will
  also present her  work on safety assessment of MRI in patients with arti
 ficial heart valves. She outlines the procedure of developing a rigorous c
 omputational model based on a full-wave time-domain analysis of Maxwell’
 s equations\, which quantifies the magnitude of resistive forces and torqu
 es applied on a variety of heart valves during MRI.\nFinally\, she will ta
 lk about applications of functional brain imaging and the role of electrom
 agnetic modelling in developing parallel-transmit technology for the safe 
 functional MRI of patients with deep brain stimulation electrodes.
