Abstract :
Electrical impedance tomography (EIT) aims at imaging the internal conductivity distribution of one cross section of the human body. OXBACT Mark III is the third generation EIT system developed in Oxford for in vivo clinical studies. It is the only EIT system in Europe based on the adaptive current method. The preliminary in vivo results show that OXBACT III has a high precision data acquisition system due to the use high speed ADC, DSP sampling patterns and its novel calibration system. The first high speed in vivo images showing lung ventilation and cardiac function of subjects are encouraging
