ABSTRACT:
Electrical tomography drive frequency selection systems and methods are disclosed. One aspect of the present invention pertains to a system for optimally selecting a drive frequency of an electrical tomography which comprises a sensor electrode stably associated with a tissue site within an internal organ of a subject for generating an induced signal based on a noise signal over a range of frequency bands, wherein an electrical field for the electrical tomography is turned off. In addition, the system comprises a noise processing module for isolating the induced signal for each frequency band over the range of frequency bands. Furthermore, the system comprises a frequency select module for selecting a drive frequency of the electrical field for the electrical tomography by comparing the induced signal for each frequency band over the range of frequency bands.
