Anomaly depth detection in trans-admittance mammography: a formula independent of anomaly size or admittivity contrast

TAM(trans-admittance mammography) aims to determine the location and size of any anomaly from the multi-frequency. A formula is proposed here that can estimate the depth of an anomaly independent of its size and the admittivity contrast. This depth estimation can also be used to derive an estimation of the size of the anomaly. Numerical simulation shows that the proposed method also works well in general settings.
