A comparison of perceived diagnostic image quality in direct digital panoramic images between standard and advanced external GOP image processing

Abstract

Objective: The objective of the present study was to study the effect of adaptive image processing (GOP processing) on the visibility of anatomical structures in direct digital panoramic images.Material and methods: The study comprised panoramic images of 50 consecutive adult individuals aged 18–60 years. Nine dentists working with dental radiology compared the structural image quality of all standard-processed and GOP-processed panoramic images for six anatomical structures, using a six-point scale for visual grading characteristics analysis.Results: For all anatomic structures a statistically significant difference in favour of the GOP was found.Conclusions: The present study shows that it is possible to improve perceived diagnostic image quality of direct digital panoramic radiography using GOP technology compared to the manufacturers’ standard processing. Manufacturers’ image-processing programs can be further developed, as there is a possibility of improving the perceived diagnostic content of an image with external processing.
