| Popis: |
Altogether 40 thymic tumor patients were investigated. Radiograms and pneumomediastinograms were subjected to processing a posteriori (increased contrast and spatial filtration). Spatial filtration improved selective analysis of spatial frequencies of imaging. Processing of images specified diagnosis of thymomas by underlining the shapes of normal and abnormal mediastinal formations and signs of invasion of the pericardium and pleura. |
