Electrical impedance tomography based image reconstruction and feto-maternal monitoring in pregnancy

Standard methods of monitoring the fetus and maternal health during labor are cardiotocogram, tocography, ultrasound and magnetocardiograpghy. These methods have some limitations in real time continuous monitoring and cause some degree of inconvenience to the patient and demand special attendance of the obstetrician also these methods cannot be used for continuous monitoring of the fetal well being. To overcome the limitations of above techniques, a non-invasive bioimpedance measuring method is proposed. This technique helps in monitoring and recording of the electrical field distribution of a closed object. The output variation on the outer surface is likely to provide information because of fetal movements and related physiological parameters. It will also help in the development of Electrical Impedance Tomography based imaging technique for a closed body system with special reference to fetal monitoring in-utero during pregnancy and labor. Also we have developed the data acquisition system of 16 electrodes with software for image reconstruction.
