To detect lung ventilation with multi-frequency EIT system.
The paper presents an EIT system based on the DDS AD9852 which could provide a multi-frequency current source and fast data acquisition. It has been used in monitoring human lung ventilation by a series of differential images. Experiments were performed successfully. The results show that the multi-frequency EIT system is reasonable, consistent and extendable. It is shown to be a suitable and reliable method of imaging human lung ventilation and the EIT technique has the potential to become a useful tool for monitoring respiration function.
