Embodiment 1
[0057] The invention utilizes other normal electrodes to perform compensation measurement on the vicinity of the disabled electrode, and provides an electrical impedance imaging method capable of improving imaging quality. The invention determines a new compensation excitation measurement scheme according to the position and serial number of the disabled electrode, compensates the sensitivity of the electrical impedance imaging system to the area near the disabled electrode, and obtains an inversion result that is basically close to the normal imaging situation.
[0058] The specific compensation ideas are as follows:
[0059] First define or abbreviate:
[0060] ①The electrode group to which excitation is applied is the excitation electrode group, and all excitation electrode groups of one scheme constitute the excitation electrode group set E;
[0061] ② The electrode group for measurement is the measurement electrode group, and all the measurement electrode groups of a gro...
