Abstract
The author has conducted theoretical study on the advantages and disadvantages of high voltage tomography.
The high voltage tomography can decrease the geometrical unsharpness by means of the use of micro-focus tube, increasing the efficiency of blurring the images of the objects outside the focused section, and can lessen the angle of rotation of the tube.
Disadvantages of this technique are that it increases the scattered rays and reduces the contrast. However, some devices will, in future, eliminate the scattered rays as much as possible and this technique should be used with better results.
