Abstract :
The first six digital radiographs of the human chest generated by the Diode Array Digital Radiography scanner of the University of Pittsburg have been evaluated using a statistically designed experiment to study image-processing methods for displaying different anatomical landmarks. Linear and nonlinear unsharp masking and local contrast stretching were used. The experimental procedure, statistical analysis of the data obtained, and the results obtained are described and discussed.
