Medically, electrical impedance tomography (EIT) is a relatively inexpensive, safe, non-invasive and portable technique compared with computerized tomography (CT) and magnetic resonance imaging (MRI). In this paper, EIT_TJU_II system is developed including both the data collection system and image reconstruction algorithm. The testing approach of the system performance, including spatial resolution...
In this paper, a set of electrical impedance tomography (EIT) system, EIT_TJU II system is presented. A physical model regarding the prior information of human thorax has been illustrated, and the sensitivities distribution comparing with the circle model is analyzed. By numerical analyzing the uniformity and the nonlinearity of the structural model are improved. The lung ventilation experiments are...
Electrical impedance tomography (EIT), as a relatively new medical imaging method, has the preferable features as inexpensive, safe, non-invasive and portable. Complementary to existing methods, it is expected to reconstruct accurate images of impedance changes in the object. One of the approaches to producing an accurately reconstructed image is the inclusion of prior information regarding the physical...
