Novel adjacent criterion method for improving ultrasonic imaging spatial resolution
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
In this letter, we present a novel approach for improving spatial resolution in ultrasonic tomography. The proposed technique modifies a Back-projection (BP) algorithm in reconstructing tomography images. We used 32-ultrasonic ...
An introduction of two differential excitation potentials technique in electrical capacitance tomography
(Elsevier B.V., 2012-06)
The investigation of this work is to analyse the sensitivity distributions using single and two differential excitation potentials techniques in order to improve the situation of: (1) non-uniform sensitivity distribution; ...

This paper describes a work carried out to design and development an ultrasonic process
tomography system. The hardware design technique is of interest of this paper. A number of
32-ultrasonic transducers have been ...
Design of an infrared tomography system for detection of bubbles
(Penerbit UTM Press, Universiti Teknologi Malaysia., 2011-08)
In this study, an optical process tomography with 2 orthogonal projections is being designed to be implemented at a vertical column modelled. The tomography system will be designed from the development of transducer pairs ...
Ultrasonic tomography - image reconstruction algorithms
(International Journal of Innovative Computing, Information and Control (IJICIC), 2012-01)
This paper focuses on image reconstruction algorithms for use in ultrasonic tomography. There are three types of algorithms namely Linear Back Projection, Hybrid Reconstruction and Hybrid Binary Reconstruction that are of ...
Study on wireless sensor based industrial tomography systems
(International Frequency Sensor Association Publishing (IFSA), 2013)
Wireless sensor technologies are promising in the field of industrial tomography system, to visualize the cross-sectional images of an industrial flow process. The aim of the paper is to review the technical and scientific ...
A review of process tomography application in inspection system
(Penerbit UTM Press, 2014)
The inspection system is crucial to ensure the system is always in a good condition. A technique that can be used for inspection system is process tomography. By promising non-destructive approach; various types of process ...
A review of ultrasonic application on non-destructive testing method for concrete structure
(Penerbit UTM Press, 2014)
Although the technique of using ultrasound has reached maturity by given the extent of the development of sensors, but the use of the various areas still can be explore. Many types of ultrasonic sensors are still at ...
A study on forward and inverse problems for an ultrasonic tomography
(Penerbit UTM Press, 2014)
This paper studies the solution for inverse and forward problems for an ultrasonic tomography. Transmission-mode approach has been used for sensing the liquid/gas two-phase flow, which is a kind of strongly inhomogeneous ...
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 ...
