The resolution of CT scanner can be decided by the size of matrix. Generally the limit of resolution is 1.5 times as large as the matrix. We used ACTA scanner (Automatic Computerized Transverse Axial Tomographic X-ray Scanner) made in the Pfizer Company of U.S.A., and researched the relation between the difference of absorption and perce ptibility by using of the eyesight discrimination as the mental evaluation method.
