Study of electric field an magnetic field affected biological cells

This paper presents the elaboration on effect of electric field and magnetic field to biological cells. Electroporation has become important parameter in treatment cancer or tumour cells. By using electric field or magnetic field, membrane cell will undergo process electroporation where membrane cell structures being altered for induce apoptosis process

Magnetic induction tomography: a brief review

Magnetic Induction Tomography (MIT) is a contactless non-invasive imaging technique that interested in mapping the passive electrical properties of a material; conductivity, permittivity and permeability. This paper presents the criteria and previous functional specification involving the development of MIT, focusing in conductivity imaging. Various ways have been implemented from a simple electronic configuration of the front-end sensory circuit, data acquisition system, reconstruction algorithm and graphical user interfacing (GUI) tools. Induction sensors are paramount as it does provide the signal source for time varying magnetic field to the coils. The advantages and limitations of MIT are also presented. Many more advancement can be expected to enhance the lack of MIT especially in spatial resolution and dynamic response of the sensor

Simulation study on non-homogenous system of non-invasive ERT using comsol multiphysics

The non-invasive sensing technique is one of the favourite sensing techniques applied in the process tomography because it has not a direct contact with the medium of interest. The objective of this paper is to analyse the simulation of the non-homogenous system of the non-invasive ERT using finite element software; COMSOL Multiphysics. In this simulation, the liquid-air medium is chosen as the non-homogenous system. A different analysis of the non-homogenous system in term of the different position of the single air, different size of the single air and the multiple air inside the vessel were investigated in this paper. As a result, the location, size and multiple air inside the pipe will influence the output of the non-invasive ERT system. A liquid-gas medium of nonhomogenous ERT system will have a good response if the air is located near the source, the size of the air is large enough and it has multiple air locations inside the pipe

Initial study on optical tomographic instrumentation system based on CMOS area image sensors

This research investigates the use of complementary metal-oxide semiconductor (abbreviated as CMOS) area image sensors in optical tomography system. The system consists of a lighting system, a measurement section and a data acquisition system. Two area image sensors are configured around a square shaped measurement section for a two projections system. Each area image sensors consists of 1600 ´ 1400 pixels with a pixel size of 2.8 ´ 2.8 micron, hence producing a high resolution system. This paper explains the initial study on activating the CMOS area image sensor model MT9D1C12STC manufactured by Micron Technology
