The Design and Implementation of a Portable EIT Telemedicine System

This paper proposes a portable electrical impedance tomography telemedicine system which supports field diagnosis and electronic medical record building. The system includes portable client endpoint, cloud-based database and central server. In order to monitor and record user's long-term state of health, it establishes personal on-line medical record database by cloud storage technique. The communication part of the system combined with 3G communication and voice broadcasting realize the field diagnosis for remote users, which send the collection of the physiological parameters back to the central server in hospital and tell users the diagnosis result quickly. Evaluation results reveal that the time consumption of a diagnosis is less than 90 seconds, and two lithium batteries can endure more than 80 times of diagnosis. Lastly, a circular salt water groove test is reported to show the performance of the electrical impedance tomography. With the advantages on portability and flexibility, the system is suitable for telemedicine application.
