| Summary: | There is a need for a medical imaging technology, that supplements current
clinical brain imaging techniques, for the near-patient and mobile assessment of cerebral
vascular disease. Microwave tomography (MWT) is a novel imaging modality that has
this potential. The aim of the study was to assess the feasibility, and potential
performance characteristics, of MWT for brain imaging with particular focus on stroke
detection. The study was conducted using MWT computer simulations and 2D head
model with stroke. A nonlinear Newton reconstruction approach was used.
The MWT imaging of deep brain tissues presents a significant challenge, as the
brain is an object of interest that is located inside a high dielectric contrast shield,
comprising the skull and CSF. However, high performance, nonlinear MWT inversion
methods produced biologically meaningful images of the brain including images of
stroke. It is suggested that multifrequency MWT has the potential to significantly
improve imaging results. |
