Dual Modality Tomography: the Image Analysis of Forward Problem

The paper presents the novel idea in process tomography which is the combination of dual modality; electrical capacitance and optical tomography for monitoring solid/gas flow measurement. dual modality tomography (dmt) system consists of eight electrodes of capacitance sensor and 16 pairs of optical sensor in one sensor plane. the data obtained from both sensors were inseries transfer to pc with control and triggered by data acquisition system. the data obtained from both sensors will then be reconstructed into image using linear back projection or iterative reconstruction algorithm. in this project, the dmt produces an image fusion, which is developed based on the adjustment of pixel values and the detection region of pixel images reconstruction between capacitance and optical tomography sensor. series of error analyses will determine the feasibility of the dmt sensors to perform as an instrument in solid flow visualization.
