摘要：

Filtered Back-Projection ( FBP) algorithm is the most common used reconstruction algorithm in Computed Tomography ( CT) systems. This paper presents the reconstruction of a 3D CT body phantom using FBP algorithm and MATLAB software. After obtaining the projections, different filters were tested: Ram-lak, shepp-logan, cosine, hamming and hann filters. In addition, a comparison was carried out for the quantitative image characteristics including the signal to noise ratio ( SNR), contrast to noise ratio ( CNR) and the spatial resolution for slices taken in three planes: axial, coronal and sagittal. Finally, the error was calculated for each reconstructed image. Initial results showed that shepp-logan and cosine filters generated most advantageous images in terms of image characteristics.
