Microwave imaging is a promising new modality
for studying brain function. In the current paper we assess the
feasibility of using a single chip implementation of an ultra-
wideband impulse radar for developing a portable and low-cost
functional neuroimaging device. A numerical model is used to
predict the level of attenuation that will occur when detecting
a volume of blood in the cerebral cortex. A phantom liquid is
made, to study the radar’s performance at different attenuation
levels. Although the radar is currently capable of detecting a
point reflector in a phantom liquid with submillimeter accuracy
and high temporal resolution, object detection at the desired level
of attenuation remains a challenge.
