Compact, Low-cost Body Cavity Screening Device

December 11, 2013 3:39 pm | by Erik Magnuson, NIJ | Comments

This study examined electric field tomography as a potential technology for developing a low-cost, non-invasive body-cavity screening device. To overcome the inherent low resolution of the tomography, researchers developed a multi-frequency method using images acquired over frequencies ranging from one to 20 MHz to build a linear model and decompose the different object types (e.g., muscle, bone, plastic) in the image.
