Multiple fan-beam optical tomography: Modelling techniques
(MDPI Publishing, 2009-11)
This paper explains in detail the solution to the forward and inverse problem faced in this research. In the forward problem section, the projection geometry and the sensor modelling are discussed. The dimensions, distributions ...
Simulation of the two-phase liquid – gas flow through ultrasonic transceivers application in ultrasonic tomography
(International Frequency Sensor Association (IFSA), 2010-01-29)
In this paper, ultrasonic transmission mode tomography was used to visualize the two phase
liquid/gas flow in a pipe/vessel. The sensing element consists of 8, 16 and 32 units ultrasonic
transceivers were used to cover ...
Gas hold-up profiles measurement using ultrasonic sensor
(Institute of Electrical and Electronics Engineers (IEEE), 2011-02)
In this letter, we present a work carried out to measure gas hold-up profiles in a liquid column using a pair of ultrasonic sensors. The gas hold-up profiles from 1.85 to 7.7 mm in diameter are of interest in this ...

Optical tomography system using microprocessor and ethernet
(Emerald Group Publishing Limited, 2010-01-01)
Purpose: Owing to the high cost of data acquisition (DAQ) card in the market, the purpose of this
paper is to develop a high speed, low-cost microprocessor and ethernet controller-based DAQ in
optical tomography system. ...
Modeling orthogonal and rectilinear mixed-modality projection of optical tomography for solid-particles concentration measurement
(Elsevier B. V., 2010-06)
In optical tomography, light attenuation/scattering methods have been used to determine average
solids concentrations in gas-solids flows. Derived from the Lambert-Beer law, the Mie theory
forms the theoretical basis for ...
Electrical resistance tomography: a review of the application of conducting vessel walls
(Elsevier, 2014-03)
Despite decades of research, the study on tomography continues to be a subject of great scientific interest. Amongst all the kinds of tomography available, electrical resistance tomography (ERT) has been chosen as the field ...
