Development Of A New Digital Radiographic Image Processing System

A new digital radiographic image processing system has been developed. The important capabilities of this system include a large image format, high image quality, on-line operation for reading, processing, and writing, and a software package for various types of image processing. A non-linear filtering technique is introduced which improves contrast of radiographic image structure while maintaining low noise in low-density areas. Preliminary clinical results demonstrate the improvements in diagnostic image quality.
