Abstract

New tissue-simulating materials that are aqueous solutions are described. Glycine is used to obtain the large permittivity of muscle at frequencies below 100 MHz. The lack of suspended solids simplifies preparation, and ensures the dielectric properties are homogeneous, stable, and reproducible. The solutions are transparent, facilitating placement of probes for measuring temperature or electric field. The optical clarity of the phantom mixture may also be desirable in a quick assessment of RF applicators by the use of liquid crystalline display sheets
