We usually measure the size of organs or other things with a caliper in the ultrasonographic diagnosis. However, it is difficult to measure the size of organs correctly, because the images obtained by U.S. are deformed or showed a false image as a result of the attenation beam and interference of the relection beam. In this examination, we studied the precision of measuring with ultrasonographic diagnostic machines, a linear, compound and sector scan system, by using trial phantom production. The result we got, comparing lateral direction with the axial direction of error, was more accurate measuring in axial direction than in the lateral direction, and in the event the phantom is more deeply positioned, the precision becomes worse for every system. Comparing each system, the compound scan system has the best precision, the linear scan system second best, the sector scan system the worst.
