The principle of operation of the hand-held fully portable LymphScanner is based on the processing of data derived from the interaction of device generated microwaves and biological material. The measured value is the tissue dielectric constant (TDC), that is converted into percentage water content (PWC), a more practical unit for clinical use. In the scanning mode, the probe, in contact with the skin, is moved from site to site.
The LymphScanner displays the PWC of an initial reference site and calculates the ratio of any subsequent reading with respect to the PWC of the selected reference site. Easy and quick scanning of potential sites of lymphedema helps to detect regional distribution of lymphedema, previously undetectable in breast, head and neck region, thorax and genital region.
