    • 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 ...

    • Ultrasonic tomography - image reconstruction algorithms 

      Mohd Hafiz, Fazalul Rahiman, Dr; Ruzairi, Abdul Rahim, Prof. Dr.; Herlina, Abdul Rahim, Dr.; Siti Zarina, Mohd Muji; Elmy Johana, Mohamad, Dr (International Journal of Innovative Computing, Information and Control (IJICIC), 2012-01)
      This paper focuses on image reconstruction algorithms for use in ultrasonic tomography. There are three types of algorithms namely Linear Back Projection, Hybrid Reconstruction and Hybrid Binary Reconstruction that are of ...
