Extraction of bioimpedance phase information from its magnitude using a non-uniform Kramers–Kronig transform.

A novel non-uniform Kramers–Kronig Transform algorithm for bioimpedance phase extraction is proposed and tested in this work. The algorithm error is studied and compared with a previously proposed phase extraction technique, also based on the Kramers–Kronig transform. Results using simulated datasets and experimental datasets confirm the excellent performance of the algorithm. [ABSTRACT FROM AUTHOR]
