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 ...
Segmented capacitance tomography electrodes: A design and experimental verifications
(Institute of Electrical and Electronics Engineers (IEEE), 2012-05)
A segmented capacitance tomography system for real-time imaging of multiphase flows is developed and presented in this work. The earlier research shows that the electrical tomography (ECT) system is applicable in flow ...
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 ...
Study of the effect of brightness after penetration of light from a lens
(Penerbit UTM Press, 2013)
There are many types of component that are able to produce light and the light is produced based on the angle and wavelength of the lens. Light penetration depends on the type of material used. The tests are done using ...

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 ...
Optical tomography: Image improvement using mixed projection of parallel and fan beam modes
(Elsevier Ltd, 2013-07)
Mixed parallel and fan beam projection is a technique used to increase the quality images. This research focuses on enhancing the image quality in optical tomography. Image quality can be defined by measuring the Peak ...
Measurement of the content of water using light penetration
(Penerbit UTM Press, 2014)
In this paper we use an electronic component to produce light which is applied in testing soft tissue penetration. We used bio tissue, a slice of apple, and non-bio tissue, paper. The voltage could be adjusted to brighten ...
Simulative study of two-phase homogenous and isotropic media imaging using magnetic induction tomography
(Penerbit UTM Press, 2014)
Magnetic induction tomography is a new non-invasive technology, based on eddy current discovery of electromagnetic induction by Michael Faraday. Through this technique, the passive electrical properties distribution of an ...
Small gas component detection using ultrasonic transmission-mode tomography system
(Penerbit UTM Press, 2014)
This paper presents the development of an ultrasonic transmission-mode tomography system for the detection of small gas components by using higher frequency ultrasonic transducers. The selection of the transducer is important ...
