A new electric impedance tomography system based on an ad-hoc low-cost and portable hardware setup combined with an efficient Lebesgue-space inversion procedure has been developed for brain stroke imaging.
The developed prototype has been validated both with numerical simulations involving a realistic model and with preliminary experimental data obtained with a phantom mimicking the shape and dielectric properties of the head, showing good detection capabilities.
EIT imaging systems have good potentialities for the detection and monitoring of brain strokes, both in the most critical early hours and during the subsequent treatment phases.
The present work and the obtained results can be useful for the development of electrical impedance tomography systems and techniques for brain stroke monitoring and diagnosis, as well as for other applications in biomedical imaging.
A Lebesgue-space inversion procedure, previously applied in microwave imaging applications, has been adapted for electrical impedance imaging, showing good regularization capabilities and improved accuracy with respect to other standard Hilbert-space approaches.
