초록
We have been used super sensitive screen/film system which is thought to be the limit of sensitivity, however, we think this method is not satisfactory. As a general radiographic rule, reduction of exposure is inconsistent with improvement of image quality, but it is necessary to challenge this rule to get better method. We tried air gap method for minimal diffuse lung shadow which is difficult to find out by our routine method. As a result, air gap method with super sensitive screen/film system(SRO 1000/TMH) showed lower exposure dose, 50% of our routine system(SRO 750/SRH with grid), and better image quality for pulmonary pattern in the lower lung field.
