A LabVIEW based data acquisition system (LV-DAS) is developed for Electrical Impedance Tomography (EIT) for automatic current injection and boundary data collection. The developed LV-DAS consists of a NIUSB-6251 DAQ card, NISCB-68 connector module and an automatic electrode switching module (A-ESM). A LabVIEW based graphical user interface (LV-GUI) is develop to control the current injection and data acquisition by LV-DAS through A-ESM. Boundary data are collected for a number of practical phantoms and the boundary data profiles are studied to assess the LV-DAS. Results show that the high resolution NIDAQ card of the DAS improves its data acquisition performance with accurate measurement and high signal to noise ratio (SNR).
