CT Image Visualization with Picture-in-Picture Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image visualization techniques in CT scanners require users to switch between multiple views of the same anatomical area, which slows down the examination interpretation process and often necessitates smaller image sizes and reduced resolution when displaying multiple views simultaneously.
Innovation Solution
A method for concurrently displaying multiple views of the same anatomical area using different processing algorithms, where each view is superimposed over a sub-portion of the image data without overlapping, allowing automatic synchronization of certain visual characteristics while maintaining image size and resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple views are displayed simultaneously on the same screen, then the user can review multiple views without switching, but the image size and resolution are reduced
Solution Approach 1:
The patent transitions from displaying multiple views sequentially (time dimension) or reducing image size (2D space) to utilizing the third dimension of screen depth through picture-in-picture technology. The primary view occupies the main display area while secondary views are displayed as smaller overlay windows, effectively using spatial layering to maintain full resolution of all views simultaneously.
2Manufacturing precision
If the user switches between different views to review multiple views, then image resolution is maintained, but the examination interpretation process is slowed down
Solution Approach 1:
The patent combines multiple separate view displays into a single integrated interface using picture-in-picture technology. The primary view and multiple secondary views are merged into one cohesive display where all views are visible simultaneously at full resolution, eliminating the need for switching between separate full-screen displays and thereby maintaining both high resolution and fast interpretation speed.
3Productivity
If multiple views are displayed simultaneously, then viewing efficiency is improved, but the number of views that can be displayed is limited by screen space
Solution Approach 1:
The patent segments the display into a primary view area and multiple secondary view areas of smaller size. This segmentation allows the main display space to be dedicated to the primary view while smaller overlay windows accommodate additional secondary views, effectively increasing the total number of views that can be displayed simultaneously without compromising the quality of the primary view or requiring excessive screen real estate.

AI summary
A method includes visually presenting a primary image (208) in a main viewport (204) of a display monitor (116). The primary image is processed with a first processing algorithm. The method further includes visually presenting a primary region of interest (210) over a sub-portion of the primary image. The primary region of interest identifies an area of interest in the primary. The method further includes visually presenting, concurrently with visually presenting a primary region of interest, at least one secondary region of interest (212, 214) over a different sub-portion of the primary image. The at least one secondary region of interest shows the same area of interest as in the primary region of interest, but processed with a second different processing algorithm.
