An absorption curve has often been used for the purpose of measuring X-ray quality. When a dosimeter of large quality dependence is used for measuring an absorption curve, the curve is different from what it is. The authors studied how to show absorption curve as it is, by using the correction factor of the dosimeter. From these studies the following were concluded : 1.The deviation included in the absorption curve depends on the form of the correction curve. 2.The fewer tangent there are in the absorption curve, the less difficult the correction is. 3.In order to correct more exactly, the X-ray quality should not be measured with half-value layer, but tangent in the absorption curve should be used for measuring energy. Moreover, many experiments showed that this correction is sufficient clinically.
