Covariances of the thermal noise currents measured at a few electrodes are shown to be related to a deterministic problem. We use the covariances obtained while selectively heating the body to recover the real power density in the body under known boundary conditions and at a known frequency. The resulting inverse problem is related to acousto-electric tomography, but where the conductivity is complex and only the real power is measured. We study the local solvability of this problem by determining where its linearization is elliptic. Numerical experiments illustrating this inverse problem are included.<\/jats:p>","DOI":"10.1137\/23m1571630","type":"journal-article","created":{"date-parts":[[2024,5,21]],"date-time":"2024-05-21T04:01:21Z","timestamp":1716264081000},"page":"984-1006","source":"Crossref","is-referenced-by-count":1,"title":["Imaging with Thermal Noise Induced Currents"],"prefix":"10.1137","volume":"17","author":[{"given":"Trent","family":"DeGiovanni","sequence":"first","affiliation":[{"name":"Mathematics Department, University of Utah, Salt Lake City, UT 84112-0090 USA.
