Image processing in digital radiography: basic concepts and applications

G T Barnes et al. J Digit Imaging. 1989 Aug.

Abstract

Digital x-ray images are routinely processed to enhance diagnostic information and to suppress irrelevant detail, and also to extract quantitative information. The basic concepts and terminology of image processing as it applies to x-ray projection radiography are discussed and defined. In general, the processing of an image involves one or more point, local, and/or global operations. Clinical examples of linear and nonlinear gray-scale and algebraic point operations are presented. Examples are also given of local operations. Included in the latter group are distortion corrections, misregistration corrections, linear filtering, and nonlinear filtering.

What is the purpose of digital image processing in digital radiography?

Image processing allows one to change the overall optical density of an image and to change its contrast. Spatial frequency processing allows an image to be sharpened, improving its appearance.

What is the purpose of digital imaging?

Quicker Answers – Using digital imaging allows us to get images almost instantaneously, in comparison to the 10-20 minutes it takes to setup and process film imaging. This will allow Doctors to review your diagnostic imaging faster than it would take with traditional radiography methods.

What are the types of image processing techniques that we use in radiography?

Point scan systems (laser-based computed radiography [CR]), linear scan systems (newer CR and some charged-couple devices [CCD]), and two–dimensional fixed array systems (CCD, direct and indirect DR) will require different forms of preprocessing to correct for system imperfections.

What are the advantages of digital image processing?

The Benefits of Digital Imaging and Impressions Impressions are stored electronically for easy access. Issues may be diagnosed immediately, as no time is needed for processing images. Precise imaging allows for improved fit of restorations. Saves time for the patient and dentist.
