MRI Hardware Development Lab

Our research is focused on an MRI hardware development that manipulates both static (B0) and RF (B1) fields from ultra-low to ultra-high field strengths. We also develop integrated magnetic field sensors/probes.

Magnetic resonance imaging (MRI) is non-invasive and non-radiating imaging modality which is efficiently used for diagnostic purposes, pre- and post-operative follow up of the patients and for guided interventions. Increased sensitivity allows increased signal-to-noise ratio (SNR) for higher resolution and shorter scan time. Higher magnetic susceptibilities at ultra-high field (UHF) are a clear advantage in several MRI techniques (fMRI, SWI and QSM). On the other hand, the wavelength in a tissue at UHF is shorter, which causes interference effects leading to B1+ field inhomogeneities. In addition, B0 field inhomogeneities are higher at UHF. In our research we investigate how to resolve and control these radiofrequency (RF) and B0 field interactions with a human body in order to unleash the full potential of the UHF MRI. The novel RF (B1+) and DC (B0) coil designs will be used for greatly improved structural, functional and metabolic imaging at UHF MRI.
