| Summary: | In order to improve the design and control of Process Tomography, the project is
presented in this study. Process tomography is a process of measuring electrical
signals by using specific types of sensor. The sensors are arranged around an object,
such as vessels or pipelines, to examine the internal characteristics of the subject. The
information on the nature of the subject is obtained by reconstructing the
measurements from the sensors into a 2-D or 3-D image. There are many methods
that can be applied in process tomography. This includes optical tomography,
resistive tomography, and acoustic tomography. The method used for this study is
Electrical Impedance Tomography (EIT). EIT is a tomographic imaging method
which enables the internal impedance ofanobject tobeimaged with the use of a ring
of external electrodes. The author had done researches and studies regarding Process
Tomography and EIT to obtain information of the process. The hardware part of the
system consists of the sensor for the signal andthe impedance measurement circuit of
the process tomography. Meanwhile, the software part includes the MATLAB
program which is used for reconstructs the signals and displays the results. In this
project, the author concentrates on the hardware circuit design and data acquisition
system for EIT.
