Dynamic Image Stream Preview for In Vivo Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vivo imaging systems struggle to effectively display large numbers of images captured during gastrointestinal tract imaging, as fixed summarized presentations lack detail and fail to distinguish between image characteristics, making it difficult for medical professionals to discern motility events and intestinal contractions.
Innovation Solution
A computer-implemented method and system that generates summarized image presentations by sorting and sampling pixels from image frames based on various parameters, creating summarized data elements such as pixel strips or graphs, which are displayed dynamically to provide a detailed preview of upcoming frames, allowing for efficient visualization of intestinal regions and motility events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a fixed summarized graphical presentation is used to display image stream data, then the amount of information displayed is reduced to fit screen space, but the detail and discernibility of image characteristics and motility events are lost
Solution Approach 1:
The patent segments the image stream data into multiple visual components: a fixed summarized graphical presentation showing overall trends, and a dynamic preview presentation showing detailed upcoming frames. This segmentation allows different levels of information to be displayed simultaneously without overwhelming the screen space, resolving the contradiction between quantity of information and detail preservation.
Solution Approach 2:
The patent adds a temporal dimension to the display by introducing a dynamic preview presentation that shows upcoming frames in sequence. This transforms the static fixed summary into a multi-dimensional display system where both summarized data and detailed previews coexist, allowing users to see both overall patterns and specific image characteristics without losing information.
2Loss of information
If all motility data from the complete image stream is presented in a graphical plot, then comprehensive motility information is provided, but the screen space required exceeds available display area
Solution Approach 1:
The patent extracts only the most relevant upcoming frames for display in the dynamic preview presentation, rather than showing all motility data. This extraction approach provides comprehensive motility information in a condensed format that fits within available screen space, allowing users to see key motility events without requiring excessive display area.
Solution Approach 2:
The patent displays a partial view of the complete image stream by showing a dynamic preview of upcoming frames rather than all frames. This partial action approach provides sufficient motility information for clinical decision-making without requiring the screen space needed to display every frame, resolving the contradiction between information completeness and display area constraints.
3Loss of information
If a detailed preview of upcoming frames is displayed dynamically, then image characteristics and motility events become discernible, but the complexity of the display system increases
Solution Approach 1:
The patent merges the fixed summarized graphical presentation with the dynamic preview presentation into a unified display system. This combination allows the system to provide detailed image characteristics and motility event discernibility while managing complexity through integrated design, where both presentations work together to convey comprehensive information without requiring separate complex systems.
4Loss of information
If the frame rate of image capture is increased to capture more motility events, then the completeness of motility data improves, but the total number of images to be reviewed increases
Solution Approach 1:
The patent performs preliminary action by displaying a dynamic preview of upcoming frames before the user reviews the complete image stream. This allows users to identify and focus on frames containing motility events of interest, thereby reducing the total number of images that need to be reviewed in detail while maintaining completeness of motility data through the preview function.
Data Source
AI summary
Systems and methods for displaying an image stream captured by an in vivo imaging device are presented. A method comprises receiving a stream of image frames captured by the in vivo device, each frame comprising a plurality of pixels. A summarized image presentation comprising summarized data elements may be generated, each summarized data element corresponding to at least one frame from the image stream. Summarized data elements are generated by ordering pixels of one or more image frames according to a first sorting parameter, sampling the ordered pixels according to a predetermined sampling scheme to acquire a subset of ordered pixels; and combining or appending sampled pixels to form a summarized data element. The summarized data elements are combined to form a summarized image presentation.
