Abstract
In this paper we present an original low cost acquisition system for computed tomographic imaging. On the first hand, the use of a linear detector consisting of sensitive elements 0.225 mm × 0.5 mm in size allows one to obtain a resolution of about 150 μm after magnification. Image quality has been assessed in terms of spatial resolution and contrast sensitivity by imaging test objects. The images ofin vitrovertebrae acquired by this experimental system show great improvement compared to the images acquired by a conventional medical scanner. On the other hand, an even better resolution (25 μm) has been obtained by using an x-ray sensitive Vidicon camera, and an industrial application is presented with advanced composite materials.
