Usually, the electrical resistance tomography is implemented by using measurements from all the available electrodes, i.e. all the boundary measurements. When the number of electrodes is very large, the reconstruction will be time consuming. The factorization method was generalized to the case of measurements on partial electrodes in this paper. The gray values in the vicinity of the partial measured...
A direct reconstruction method for three-dimensional (3-D) electrical resistance tomography was introduced by using the factorization method. Compared with the traditional image reconstruction algorithms based on the sensitivity/Jacobian matrix, the conductivity distribution in any part of the 3-D region of interest can be obtained directly and independently. A new way to calculate the Neumann-to-Dirichlet...
A direct reconstruction method for 3D electrical resistance tomography was introduced. Compared with the traditional image reconstruction algorithms based on the sensitivity/Jacobian matrix, the conductivity distribution in any part of the three dimensional region of interest can be calculated directly and independently, by using the factorization method. Simulated data for electrical resistance tomography...
A factorization method was introduced to electromagnetic tomography (EMT) in this paper. Compared with the traditional methods based on the sensitivity theorem, the proposed method can generate the reconstructed images directly. Neither matrix inversion nor iterations is needed in the reconstruction process. The reconstruction process is simple, as the test function is calculated according to the...
The factorization method was introduced to electrical capacitance tomography for sensors of non-circular cross sections in this paper. Unlike the traditional methods based on sensitivity theorem, it is a direct algorithm of the image reconstruction, as neither matrix inversion nor iterative process is needed. The reconstruction process was simple, as the test function was calculated according to sensors...
