Noninvasive method for measuring the electrical properties of deep tissues using an open-ended coaxial probe

Local Tissue Water in At-Risk and Contralateral Forearms of Women with and without Breast Cancer Treatment-Related Lymphedema

“…It consists of a cylindrical probe connected to a control unit that displays the tissue dielectric constant when the probe is placed in contact with the skin. The physics and principle of operation has been well described [7][8][9]25,26 . In brief, a 300 MHz signal is generated within the control unit and is transmitted to the tissue via the probe that is contact with the skin.…”

“…In brief, a 300 MHz signal is generated within the control unit and is transmitted to the tissue via the probe that is contact with the skin. The probe itself acts as an open-ended coaxial transmission line 7,25 . The portion of the incident electromagnetic wave that is reflected depends on the dielectric constant of the tissue, which itself depends on the amount of free and bound water in the tissue volume through which the wave passes.…”

“…Suitable measurements for routine use include arm volumes [1][2][3][4] , arm bioimpedance 5,6 and local tissue water determined by measuring the tissue dielectric constant [7][8][9][10] at various sites and tissue depths [11][12][13] . Because BCRL initially develops in skin and subcutis 14 …”

Application of microwaves dielectric spectroscopy for controlling pork meat (Longissimus dorsi) salting process

“…Dielectric spectroscopy is one of the most important techniques for chemical and physical material analysis in some research fields: medicine (Aimoto and Matsumoto, 1996;Fear et al, 2002Fear et al, , 2003Peebles et al, 1992), pharmaceutical industry (Smith et al, 1995), science of materials (Adous et al, 2006;Goy et al, 1992;Martín et al, 2004). It has also been widely used in food technology for controlling some quality factors: salt content (De los Reyes et al, 2006Reyes et al, , 2007Kent et al, 2000;Shiinoki et al, 1998), detection of milk bacteria (Váczy and Semberg, 2003).…”

Microwave sensing for an objective evaluation of meat ageing

“…Many efficient methods of non-destructive monitoring, based on the measurement of reflection and transmission coefficients of electromagnetic waves at microwave frequencies, have also been proposed for medical applications (Aimoto and Matsumoto, 1996) and process control in the pharmaceutical industry (Smith et al, 1995).…”
