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; ...
The hardware design technique for ultrasonic process tomography system
(International Frequency Sensor Association Publishing (IFSA), 2012-06)
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 ...
A review of tomography system
(Penerbit UTM Press, 2013)
Tomography system is a method that being used to reconstruct a cross sectional image in vessel or pipeline. This method is widely used in medical and industrial fields. The aim of this paper is to provide an overview of ...
Development of parallel and fan-shaped beam mixed-projection optical tomography
(International Frequency Sensor Association Publishing (IFSA), 2012-05)
Parallel and fan shaped beam are two common projections that had been used widely in
optical tomography system. These projections never have been merged before in the process of
tomography area. In this paper, some ...
A study of a two phases medium in pipe vessel using gaussian filter method and k-NN classifier
(IOS Press, 2013-07-03)
In this paper we present the existence and uniqueness of solutions to the stochastic problem to determine two phase level of gas and water in the industrial pipe line. In order to distinguish the level phases in a vessel ...
Advancements in Transmitters and Sensors for Biological Tissue Imaging in Magnetic Induction Tomography
(MDPI AG, 2012-05-29)
Magnetic Induction Tomography (MIT), which is also known as Electromagnetic Tomography (EMT) or Mutual Inductance Tomography, is among the imaging modalities of interest to many researchers around the world. This noninvasive ...
Sensor modeling for portable Electrical Capacitance Tomography system using simulation by COMSOL Multiphysics
(Innovative Computing, Information and Control (ICIC) International, 2012-10)
This work presents the development process for modeling a 16-segmented portable ECT (Electrical Capacitance Tomography) sensor (using FEM software package COMSOL Multiphysics). The physical sensors are 3D dimensional but ...
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 ...
