    • An introduction of two differential excitation potentials technique in electrical capacitance tomography 

      Elmy Johana, Mohamad, Dr.; Ruzairi, Abdul Rahim, Prof. Dr.; Leow, Pei Ling, Dr.; Mohd Hafiz Fazalul, Rahiman, Dr.; Omar Mohd Faizan, Marwah; Nor Muzakkir, Nor Ayob; Herlina, Abdul Rahim, Dr.; Fazlul Rahman, Mohd Yunus (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; ...

    • Novel adjacent criterion method for improving ultrasonic imaging spatial resolution 

      Mohd Hafiz, Fazalul Rahiman, Dr; Ruzairi, Abdul Rahim, Prof. Dr.; Herlina, Abdul Rahim, Dr.; Nor Muzakkir, Nor Ayob (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 ...

    • Tomographic reconstruction of a multi-attenuation phantom by means of ultrasonic method 

      Mohd Hafiz, Fazalul Rahiman, Dr; Ruzairi, Abdul Rahim, Prof. Dr.; Herlina, Abdul Rahim, Dr. (Springer Science+Business Media B.V., 2012)
      This paper presents a work on tomography reconstruction of a multi-attenuation phantom by means of ultrasonic method. A transmission-mode approach has been used for the sensing modality. The reconstruction has been conducted ...
