Abstract:
Electrical Impedance Tomography (EIT) is a
technique to image the conductivity distribution that has been
used in many medical applications. For lung application, EIT
can image lung ventilation with a good temporal resolution
which is helpful for diagnosis and providing information for
lung recovery. The image reconstruction of EIT is usually based
on a single excitation frequency. The reconstruction also usually
uses a common chest model instead of an exact chest model due
to limited availability resulting in a modeling error in the
reconstruction process. In this study, the change in conductivity
of frequency difference was investigated whether it can be used
for lung ventilation monitoring. A method to construct a
frequency difference image was proposed. Some techniques to
reduce the influence of modeling error were also investigated
whether they could improve the reconstruction or not. An
experiment result on a subject showed that the frequency
difference method can be used for monitoring the respiration
activity with higher discriminability i.e. the conductivity change
in each lung region was clearly seen. However, the singlefrequency
method still provided a better shape of the change
that was consistent with the lungs shape. The implementation
of the modeling error reduction could significantly increase the
image amplitude for both methods, but it could reduce the
artifacts for only the single-frequency method
