II. Description

Electrical Impedance Tomography (EIT) is a non-invasive
imaging technique that has applications in the crack detection ,
medical field [1] and industrial processes. For instance,EIT has
been used to image lung functions.
Additionally, EIT has been used
to determine pulp consistency,
which can be integrated into a
process control loop in the paper
manufacturing process.

EIT is based on the principal that different materials have
different electrical properties. EIT imaging exploits these
properties (i.e. impedance) to produce a cross sectional image in
a non-invasive manner.

    VIII. Problem Faced in Procurement
    of Data Acquisition Equipment :
    ~RM 44, 000
   Funds were not sufficient to make the purchase in
    May 2007
   Written letter to MOSTI, June 2007, for early
    release of funds for the purchase
   Dec. 2007, No reply............
   Funds were made available by RMC-UNITEN from
    other resources
   Jan 2008, restart the purchasing activity as the
    quotation expired and re-process the procurement
   April 2008 – Agent of the Equipment ‘National
    Instrument’ is in receipt of supplying the
    equipment now
IX. Request for Extension In Project
• Request for one year extension
• Sufficient budget
• Extension is requested to complete the Imaging
