Research Areas: MRI Near Metal Implants
While working in the Applied Science Laboratory at GE Healthcare, Kevin Koch, PhD, as one of the inventors of 3D Multi-Spectral Imaging (3D-MSI). The trade names for this technology are MAVRIC SL (GE Healthcare) and SEMAC (Siemens Healthcare). The Koch Laboratory at MCW is continuing development of technical advances in 3D-MSI. In addition, the team is working with clinical partners at a variety of institutions to further the clinical utility of existing clinical 3D-MSI implementations.
Research Area: Quantitative Susceptibility Mapping
Quantitative susceptibility mapping (QSM) is a powerful tool to identify a specific physical characteristic parameter at each pixel in an MRI image. QSM relies on MRI signal phase measurements, which are proportional to the local magnetic field, which is correlated to the local tissue susceptibility. The computation of the susceptibility from measured MRI signal requires a numerically challenging mathematical inversion over three-dimensional space. We are currently investigating methods of improving this inversion, rendering the resulting maps potentially viable for quantitative assessment of neurological conditions related to traumatic brain injury and cancer.
