Microtomography systems usually are laboratory devices designed for defectoscopy and three- dimensional nondestructive testing. Initial data acquisition for X-ray and optical microtomography takes a relatively long time because of the low radiation intensity of fine- focus sources. It is therefore impracticable to employ expensive specialized processors for data input and image reconstruction. A more practical approach involves the use of image processing systems based on personal computers. It is shown that such equipment can handle the tasks of data acquisition and 3-D image reconstruction and visualization very effectively. The efficiency of a microtomograph system depends on the capabilities of software and of the system of data input into the computer. To speed up image reconstruction, use is sometimes made of a specialized coprocessor to carry out convolution with back projection. The software package usually contains programs to perform the operations of image reconstruction and 3-D visualization.
