Virtual Presentation Navigation via Contrast Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical imaging technologies face inefficiencies in selecting, ordering, displaying, and navigating virtual presentations of body portions generated during medical examinations, leading to significant time spent by practitioners searching for specific presentations.
Innovation Solution
A method and system that provide unique identifiers for virtual presentations, allowing practitioners to efficiently select, order, display, and navigate presentations by generating lists of studies and presentations with characteristic items, and assigning presentations to these lists based on acquisition settings and processing features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple virtual presentations with different contrasts are generated during a medical study, then the comprehensive information available for assessing medical conditions is improved, but the time required to search for and select specific presentations increases
Solution Approach 1:
The patent segments the presentations into different lists organized by contrast types (e.g., bone contrast, soft tissue contrast, blood vessel contrast). Each list contains presentations with specific contrast characteristics, allowing users to quickly navigate to the relevant contrast group without searching through all presentations sequentially. This segmentation resolves the contradiction by maintaining comprehensive information availability while reducing search time through organized categorization.
Solution Approach 2:
The system performs preliminary organization of presentations into contrast-based lists during or after the medical study, before the user needs to search for specific presentations. By pre-sorting and categorizing presentations according to their contrast characteristics, the system eliminates the need for time-consuming searches while preserving all presentation information for comprehensive assessment.
2Ease of operation
If presentations are organized in chronological order only, then the simplicity of the listing is maintained, but the ease of finding specific contrast types deteriorates
Solution Approach 1:
The patent creates multiple lists segmented by contrast types while maintaining chronological order within each list. Each contrast-based list preserves the temporal sequence of presentations but organizes them by contrast characteristic, allowing users to easily identify and access specific contrast types without complicating the overall structure. This segmentation approach maintains operational simplicity while improving contrast type detection.
Solution Approach 2:
The system adds an additional organizational dimension beyond chronological order by introducing contrast-based categorization. Presentations are arranged along two dimensions: time (chronological order) and contrast type (categorical grouping). This dimensional change allows users to navigate presentations by contrast type while preserving temporal context, making contrast identification easier without sacrificing listing simplicity.
3Device complexity
If all presentations are displayed together in a single list, then the device complexity is minimized, but the productivity of the practitioner deteriorates due to increased search time
Solution Approach 1:
The patent segments the single presentation list into multiple contrast-based lists, each containing presentations with specific contrast characteristics. This segmentation improves practitioner productivity by allowing quick access to relevant contrast types without requiring complex search functions or navigating through all presentations sequentially. The system maintains relative simplicity by using straightforward list-based organization rather than complex interactive filtering mechanisms.
Solution Approach 2:
The system performs preliminary organization of presentations into contrast-based lists, preparing the data structure before the practitioner needs to access specific presentations. This pre-organization improves productivity by eliminating the need for time-consuming searches while maintaining simple list-based navigation. The preliminary categorization action occurs during system setup or data ingestion, avoiding added complexity during the actual viewing and assessment process.

AI summary
A method and a system for navigating virtual presentations such as images of a body portion that are generated during medical examinations (studies). The method includes a step of providing in a user interface a list of studies, a list of presentations and a presentation of the body portion. The list of studies includes items that are characteristic for a kind of study. The list of presentations comprises items that are characteristic for a kind of presentation. The presentation displayed in the user interface depends on the item selected in the list of studies and the item selected in the list of presentations.
