Advanced Processing Capabilities of FCR 1. Image Processing (Gradation/Spatial Frequency) Because CR images are digital, various types of image processing can be utilized to enhance the image's diagnostic quality. The typical kinds of image processing that have been used in daily practice include gradation processing, spatial frequency processing, and dynamic range control processing. Gradation processing is done via computer to optimize image contrast and optical density. Image contrast can be adjusted as desired, in accordance with the type of component and diagnostic purpose. Image processing improves diagnostic accuracy and expands diagnostic scope. Two types of image processing that are involved are: gradation processing and spatial frequency processing. |
