ABSTRACT:
The subject invention pertains to an imaging technique and apparatus which can utilize an array of RF probes to measure the non-resonant thermal noise which is produced within a sample, such as a body, and produce a non-resonant thermal noise correlation. The detected noise correlation is a function of the spatial overlap of the electromagnetic fields of the probes and the spatial distribution of the conductivity of the sample. The subject technique, which can be referred to as Noise Tomography (NT), can generate a three-dimensional map of the conductivity of the sample. Since the subject invention utilizes detection of the thermal noise generated within the body, the subject method can be non-invasive and can be implemented without requiring external power, chemicals, or radionuclides to be introduced into the body. The subject imaging method can be used as a stand along technique or can be used in conjunction with other imaging techniques.
