摘要： Security scanning devices based on electrical tomography, including tomography systems based on the measurement of capacitance (ECT) and electromagnetic tomography (EMT), in combination with knowledge-based image analysis and understanding. Each device comprises a sensing head or transducer, sensing electronics, image reconstruction and image analysis microprocessor (either microcontroller, DSP, laptop or desktop PC), a display unit and accompanying software for identifying dangerous materials and items. The security scanning devices enable enhancement of image resolution with ECT and EMT. More sensors, more sensitive circuits and flexible/optimal measurement protocols may be employed for obtaining more independent measurements and enable implementation of data fusion to combine the complementary sensitivity of ECT and EMT to different material properties, while providing architecture to implement image knowledge bases, which may characterize objects, whose image attributes are acquired from multiple sensors.

摘要： A method and apparatus for producing particle density map images of fluidised particles by electrical capacitance tomography (ECT) in a fluidised bed apparatus allows for measuring online the liquid content of fluidised particles during the fluidisation process and for recalibration of the fluidised particle permittivity during fluidisation, allowing for online recalibration of an ECT system when the liquid content of particles changes, such as for fluidised bed drying or granulation processes. Recalibration measurements are made using reference electrodes positioned to measure the capacitance of the densely fluidised particles near the side walls of the fluidised bed. The electrodes of an ECT sensor array may be used to make the recalibration measurements which can be used to provide online liquid content measurement, such as moisture content, for the fluidised particles without stopping out stopping fluidisation. The liquid content information may be used for process control. The method may also be used to provide separate images for solids distribution and for total liquid distribution across a plane being imaged.
