Multi-Modal OCT GUI for Vessel Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of optical coherence tomography (OCT) in vascular diagnosis face difficulties in interpreting tomography images due to information overload, making it challenging to correlate with other imaging modalities effectively.
Innovation Solution
A Graphical User Interface (GUI) is developed to allow users to control and manipulate multiple imaging modalities, including OCT, near-infrared fluorescence (NIRAF), and angiography, providing intuitive views such as carpet, 3D rendering, lumen diameter, and longitudinal views, with control bars for synchronized display and highlighting of NIRAF data, enabling a comprehensive understanding of vessel structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple imaging modalities are displayed simultaneously to provide comprehensive vessel information, then the completeness of information is improved, but the complexity of image interpretation deteriorates due to information overload
Solution Approach 1:
The patent divides the display into multiple independent panels, each dedicated to a specific imaging modality (OCT, NIRAF, angiography). This segmentation allows comprehensive information to be presented while reducing interpretational complexity by organizing data into discrete, manageable sections with dedicated control bars for each modality.
Solution Approach 2:
The patent introduces control bars as intermediary elements between the user and the imaging data. These control bars provide intuitive manipulation interfaces for each imaging modality, acting as mediators that simplify the interaction with complex multi-modal data and enable synchronized viewing without overwhelming the user.
2Measurement precision
If detailed multi-modality information is provided to enhance diagnostic accuracy, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent creates a universal display framework that accommodates multiple imaging modalities through a consistent interface design. The same control bar mechanism works for all modalities (OCT, NIRAF, angiography), providing multi-functionality that enhances measurement precision while avoiding proportional increases in interface complexity.
Solution Approach 2:
The patent adds a temporal/synchronized dimension to the display by enabling control bars to operate simultaneously across different imaging modalities. This allows precise correlation of structures across modalities without requiring complex spatial arrangement, as the synchronization provides the organizing dimension.
3Loss of information
If all imaging modalities are displayed with full detail to provide comprehensive view, then the information completeness is improved, but the ease of manipulation deteriorates
Solution Approach 1:
The patent segments the manipulation control into separate control bars for each imaging modality. This segmentation maintains full detail display for comprehensive information while improving ease of manipulation by allowing users to independently control each modality through dedicated, simplified interfaces rather than a single complex control system.
Applied Scientific Principles

Function Achieved in This Case
The GUI enhances the ability to focus on areas of interest, providing a clear and comprehensive view of structural vessel information using multi-modalities, allowing for more targeted and accurate analysis and decision-making during medical procedures.
Implementation Method 1
The aim of the OCT techniques is to measure the time delay of light by using an interference optical system or interferometry, such as via Fourier Transform or Michelson interferometers. A light from a light source delivers and splits into a reference arm and a sample (or measurement) arm with a splitter (e.g., a beamsplitter). Both beams combine (or are recombined) at the splitter and generate interference patterns.
Implementation Method 2
near-infrared fluorescence (NIRAF)
