Abstract
The conventional ways to evaluate the detectability of ECT probes are usually based on some type of Maxwell equations with use of the FEM or BEM method[1]. Though these approachs can give relatively accurate eddy current field and corresponding impedance, the numerical calculation needs a lot of computer memory and CPU time. This causes them a drawback in ECT probe optimization procedures. Moreover, probe optimization is not only related to the best choice of some parameters of a given probe configuration, but the configuration parameters such as the number and arrangement of exciting and pick-up coils also need to be adjusted and modified. Since the numerical method can not give us a clear image to connect the eddy current to the exciting field, the discovery of a new excellent probe is difficult if this approach is not improved.
