Abstract:
Objective To display space occupying lesions of spine,mediastina and lungs behind heart and small lesions in bilateral pulmonary fields in the same chest film without changing the exposure doses which were now used for routine chest images.Methods The distribution of current intensifying screens' intensifying materials were changed and reasonable technical processes were given.High-velocity and middle-velocity intensifying materials were placed in center and in two sides of the screen respectively.Results Tests in seven volunteers using the new kind intensifying screens demonstrated that diseases could be better shown than normal intensifying screens in chest images.Conclusion The renovation can provide more and clearer and richer stratifications of image information to help chest X-ray diagnoses.
