Care & Cure Science Café
14 January 2022 @ 15:00 - 16:00
On the 14th of Januari, from 15:00 until 16:00, the next Care & Cure Science Café will be held!
C3Te has invited Dr. Irena Zivkovic to talk about “Ultra-High Field MRI – How high can we go?”
Irena Zivkovic – Integrated Circuits (IC) and Electromagnetics (EM) group of Electrical Engineering.
Magnetic resonance imaging (MRI) is the most versatile medical imaging platform that provides superior soft tissue contrast for both body and brain imaging. It has become a favorite tool in the research settings, especially within neuroscience, because it can map not only the anatomy but also neuronal activation and function without the use of radiation. Scientists have worked on increasing the sensitivity of MRI, image contrast and spatial resolution. One obvious way to increase resolution is to increase the spin polarization via increasing the static magnetic field B0 in MRI. However, a consequence of a larger static magnetic field B0 is a higher Larmor frequency and a shorter wavelength. This increased frequency complicates RF electronics and detector design and therefore the technology developed for lower fields such as 3 Tesla is difficult to adapt and transfer directly to the ultra-high field 7 Tesla. This talk will discuss some of my recent developments of the RF technology that allowed high-resolution high-SNR ultra-high field imaging at 7T. I will also present my contributions to the B0 field shimming at 9.4T MRI.
Due to the Corona situation the Care & Cure Science Café will be in the form of a webinar (participants will receive the MS Teams link on the day of the webinar).
