The Design Study Of Abdomen Electrode System For EIT

Electrical Impedance Tomography is that reduce the images of body's electrical impedance through characteristic of inside body's electrical impedance. Comparing the technology of tradition imaging, EIT can finish faction image, .Because EIT doesn't use nuclide or radial, it have no damnification to body and could be used time after time. Now days, EIT as a new technology, was regarded by all the scholars inland and abroad, and became hotspot of research. Electrode system is an important part of EIT, which is a metrical part of connecting the human body to electrical instrument and play a role in collection and conduct of signal. We studied the following research by imbursing of national natural science fund.1. Using the method of four electrodes to compare the electrical impedance characteristic of different materials to body's contact, and using electrode materials include silver, silver chloride, cuprum and sliver electric conduction cloth, We compared electrodes of different materials through experiments. As a result, we approved the electrodes of silver chloride is the best electrodes to EIT. Through these experiments, we can provide base to electrodes materials for electrodes system.2. Using sliver electrodes as hypodermic electrodes, using silver chloride electrodes as epidermal electrodes to monitoring simulating intraperitoneal bleeding, and comparing the characteristic of hypodermic electrodes and...
