Summary
Commercial dental imaging software offers limited image processing tools, hindering analysis. Standardized terminology and enhanced features are needed for better dental radiology software.
Area of Science:
- Digital imaging
- Radiology
- Image processing
Background:
- Commercial software for direct digital dental imaging is widely used.
- Image processing capabilities within this software are crucial for diagnostic accuracy.
- A lack of standardization in image processing tools complicates software comparison.
Purpose of the Study:
- To identify and analyze image processing algorithms in commercial dental imaging software.
- To map these algorithms to a standardized nomenclature.
- To evaluate the functionality and naming conventions of image processing tools.
Main Methods:
- Evaluated thirteen commercial dental imaging software programs.
- Utilized a synthesized test image with various features (gray scale ramps, noise).
- Classified algorithms for display, point processing, pseudo-coloration, spatial filtering, frequency domain filtering, measurements, and annotations.
Main Results:
- All programs offered basic gray-scale display and measurement tools.
- Image processing and enhancement features were found to be limited and varied across programs.
- Inconsistent naming and implementation of functions were observed, with some using terms inappropriately.
Conclusions:
- Commercial dental imaging software generally lacks comprehensive image processing and enhancement functions.
- The arbitrary naming of functions hinders software comparison and evaluation.
- Standardized terminology and expanded functionality are recommended for dental radiology software.
