We investigate a multifrequency impedance imaging technique that has recently been suggested for mammography screenings. This MUSIC type technique uses boundary voltages generated by time harmonic (AC) boundary currents with the same spatial distribution but different driving frequencies. We prove that the method will always find a single small focal lesion in two or three space dimensions. Concerning the two dimensional case we also discuss the potential of the method to find and separate multiple inclusions.
