| Abstract: | A new method for measuring the density of the anti-scatter grid using digital filtration technique was introduced in this paper. In the technique, a computer was applied to process all the data in real time. The practical results showed that this method is more objective and accurate than the X-ray projection measuring method, and further, the testing efficiency is enhanced tenfold. |
