Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional panoramic radiography devices face challenges in producing sharp and clear images of dental arcs due to mismatched photographing trajectories and limited depth resolution, making it difficult to examine internal structures like the inner and outer roots of molars with a single panoramic image.
Innovation Solution
A panoramic radiography device that produces primary and secondary panoramic images using different image layers, enhancing depth resolution by reconfiguring image layers based on x-ray image frame data and displaying them together through a graphic user interface, allowing for improved examination of dental structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single panoramic radiograph is produced using conventional photographing trajectory, then the device complexity is low, but the measurement precision of dental structures (especially depth resolution) is insufficient
Solution Approach 1:
The patent divides the panoramic radiograph into multiple image layers corresponding to different depth ranges. Each image layer is focused on a specific depth plane, allowing selective examination of dental structures at different depths (e.g., inner roots vs. outer roots of molars). This segmentation transforms a single low-resolution image into multiple high-resolution depth-specific images.
Solution Approach 2:
The patent introduces a depth dimension by creating multiple image layers along the z-axis (depth direction). Instead of a single 2D panoramic view, the system generates stacked 2D image layers that represent different depth planes, effectively adding a third dimension to the panoramic radiograph for enhanced depth resolution.
2Measurement precision
If multiple image layers are produced and displayed together, then the measurement precision of dental structures is improved, but the ease of operation increases due to complex interface requirements
Solution Approach 1:
The patent merges multiple depth-specific image layers into a single integrated graphical user interface. The interface displays multiple image layers simultaneously in a coordinated manner, allowing users to navigate and examine different depth planes without switching between separate applications or complex configurations. This merging maintains high measurement precision while simplifying user interaction.
3Loss of information
If conventional single panoramic radiograph is used, then the device complexity is low, but the information completeness of dental structures is insufficient
Solution Approach 1:
The patent segments the dental arch into multiple depth planes, with each image layer capturing anatomical structures at a specific depth. This segmentation prevents information loss by ensuring that structures at different depths (e.g., overlapping tooth roots) are clearly separated and individually visible, providing complete information that would be obscured in a single conventional panoramic image.

AI summary
The disclosure is related to a panoramic radiography device. The panoramic radiography device may include an image processor and a viewer module. The image processor may be configured to produce a primary panoramic image using a first image layer and a secondary panoramic image using a secondary image layer based on a plurality of image frame data, wherein the second image layer is different from the first image layer in at least one of a number, a position, a shape, an angle, and a thickness. The viewer module may be configured to i) provide a graphic user interface having a primary display area and a secondary display area arranged at a predetermined position of the primary display area, ii) display the primary panoramic image at the primary display area, and iii) display a part of the secondary panoramic image at the secondary display area, wherein the part of the secondary panoramic image corresponds to the predetermined position.
