Bioimpedance has shown potential as a method for characterising biological tissue with the use of the tetrapolar electrode configuration. This configuration has been shown to distinguish between normal squamous epithelium and Cervical Intra-epithelial Neoplasia (CIN) . The tetrapolar configuration has also been shown to produce anomalous results in the form of an increase in measured impedance when a low impedance lesion is located between a drive and measurement electrode . We have investigated a possible solution to this problem using bioimpedance mapping employing an array of 25 (5x5) electrodes. The array allows 64 individual tetrapolar measurements to be taken on 16 locations giving an impedance map of 49 mm2 on the surface of a tissue sample. Multiple measurements at each location reduce the chance of anomalous results since these can later be identified and excluded. Preliminary results on bovine blood have shown good separation of the measured impedance between areas of different haematocrit and provided a visual representation of the surface impedance. Impedance maps have been obtained for a range of haematocrit between 0 - 80%.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
