Study on Data Acquisition and Image Characteristics of Brain Multifrequency EIT in Healthy People and Patients With Brain Diseases

For subjects who received clinical trials, 16 electrodes were placed equidistantly in their head, and brain EIT data were measured at 9 frequencies in the range of 21 kHz to 100 kHz by applying a current RMS of 176 microamps.MFEIT image sequences were obtained according to certain imaging algorithms.
