Abstract

Abstract

The measurement of repeatability for X-ray source position between several experiments was proposed. The difference between several images of the same object indicated the repeatability of the X-ray source position. First, a shell object was radiographed several times to get several images. And then the edge of each image was detected. By fitting the edge data of the image, the center position of the object in each experiment was obtained. The dataset of the center position showed the repeatability of the X-ray source position. The experiment results showed that the shift of the X-ray source position was less then 0.1 mm.
