== C=eboifk^=^_ari=o^efj P = ^Äëíê~ÅíK= This paper presented image reconstruction algorithms for use in ultrasonic tomography. There are three types of reconstruction algorithms namely Linear Back Projection, Hybrid Reconstruction and Hybrid Binary Reconstruction. The algorithms have been evaluated on ultrasonic tomography system based on several known phantoms and real objects. The performance of the algorithms have been analysed and discussed at the end of the paper. hÉóïçêÇëW= Reconstruction

Terdapat tiga jenis algoritma pembangunan iaitu Linear Back Projection, Hybrid Reconstruction dan Hybrid Binary Reconstruction. Algoritma tersebut telah diuji ke atas sistem tomografi ultrasonik berdasarkan kepada beberapa bayang yang telah dikenalpasti dan objek -objek sebenar. Prestasi algoritma tersebut telah di analisa dan bincangkan pada bahagian akhir kertas ini h~í~=âìåÅáW= Algoritma pembangunan; tomografi ultrasonic; pemprosesan image; mabuk NKM= fkqolar'qflk= = Most of the work in process tomography has focused on the back projection technique. It is originally developed for the X-ray tomography and it also has the advantages of low computation cost [1]. The measurements obtained at each projected data are the attenuated sensor values due to object space in the image plane. These sensor values are then back projected by multiplying with the corresponding normalized sensitivity maps [2] . The back projected data values are
