ELECTRICAL PROPERTY ENHANCED TOMOGRAPHY (EPET) APPARATUS AND METHOD

摘要

Enhanced information on the electrical properties of the subregion (208-216) of a sample (204) is generated by an enhanced tomography (EPET) apparatus (600) connected to a tomograph device, wherein the EPET apparatus (600) holds a voltage constant, and measures the electrical current of the sample (204) inserted within the EPET apparatus (600). A matching medium (602) is applied to the sample (204) inserted within the apparatus (600). A matching medium (602) is applied to the sample (204) such that when the sample (204) is placed within an electromagnetic field generated by the EPET apparatus (600), the matching medium (602) contacts the segmented sensor plates (606) of the EPET apparatus (600), and allows the detection of the net total charges Q on the surface (202) of the sample (204). The EPET apparatus (600) uses these net total charges Q in the calculation of additional information on the electrical properties of the sample (204) by using the scale factor method or the iteractive correction method.
