摘要：
Computed tomographic images of soft materials are obtained using differential attenuation and transmission method with a tube source of X-rays, for samples like walnut, brew tooth and peaches in order to know the interior properties of the material at optimum energy in terms of attenuation coefficient. At optimum energy it is possible to calculate the three-dimensional representation of inner and outer surfaces of the object. The interior of the soft material is visualized using the novel soft ware in order to know the distribution of attenuation coefficient in terms of density. The results for walnut, brew tooth and peaches are presented as a set of images from the internal parts of the sample. (C) 2002 Elsevier Science Ltd. All rights reserved.
