Impedance imaging using linear electrode arrays.
The characteristics of using a linear array of electrodes for impedance imaging are examined. The advantages of a linear array include known electrode position, localised resolution, and mobility, but there are some disadvantages. The problems of the choice of data set, and of the range of measurements are examined. The results of investigations into resolution and sensitivity are presented, and also of some preliminary in vivo measurements. It is concluded that a linear array may have possible clinical applications.
