Abstract

We have developed of the exposure technique for the chest radiography to get different contrast in left and right lung fields simultaneously for the effective diagnosis, I.E., get high contrast to detect tuberculosis, dispersal shadow or exudative lesions of early tuberculosis and get better sharpness and wider latitude to detect growing lesions of lung cancer or lesions overlapped with bones. As a result, by using an additional filter Cu 1.2mm with BX-III screen side and sheet of yellow cellophane on BF-III screen side at the conventional KV ($80KV{\sim}100KV$) for the chest X-ray, we can get similar densities in both left and right lung fields and, thus, this method is considered to be very effective for the quality diagnosis for the routine chest radiography.
