From: A novel time-difference electrical impedance tomography algorithm using multi-frequency information
tdEIT algorithms | Advantages | Disadvantages |
---|---|---|
BP | Fast imaging speed [6] | Smearing artifacts [9] |
GN | Fast imaging speed [3] Generally performs better than BP [5] | Target boundary blurred [1] |
TV | Sharp edges preserved [12] | Iteration needed [12] Multiple parameters adjustment needed [12] |
GREIT | Uniform amplitude response [5] | Training set required [5] |
SC | Multi-frequency information integrated Automatic extraction of single tissue Image noise significantly reduced | Tissues conductivity spectra required |
