Solve Internal Problems

By DE Editors

DYNAEIT from DynaFlow Inc. (Jessup, MD) is a suite of algorithms basedon BEM (boundary element method) technology for solving EIT (electricalimpedance tomography) problems.

EIT builds a 3D conductivity map depicting material distributionswithin a container. The DYNAEIT algorithms use what DynaFlow calls"CPU-efficient methods,” such as a dipole approximation method and asingular boundary element method, to solve current distributions for aknown conductivity distribution in the imaged object. To solve imagereconstructions using the measured voltages and/or currents, theDYNAEIT algorithms use multidimensional minimization procedures, suchas Powell’s Direction Set Method, the Downhill Simplex Method, GeneticAlgorithms, and multi-objective minimization based on Pareto sets.

DynaFlow expects that the DYNAEIT algorithms to be applied in medicalimaging and multiphase flows in chemical, oil and gas, energy, andaerospace. They are also said to be suitable for non-destructivetesting of structures and materials, imaging of underground water pathsand container leakage, and chemical reactive flows as well asarchaeology and the detection of buried objects. Initial efforts todevelop DYNAEIT were funded by two Small Business Innovation Researchawards from the National Science Foundation.
