Solution Overview
Problem
Current systems lack efficient methods for synchronously storing video image data with other data from medical procedures, such as device and measurement data, especially in high-frequency surgeries, where time-critical processes are difficult to assess due to inadequate evaluation options and high effort required for synchronization.
Innovation Solution
A method and system that embeds treatment, device, diagnostic, and measurement data directly into video images by replacing pixel data in identified target areas, ensuring time-synchronous recording and storage, using a signal processing device to process and compress the modified video image data for efficient evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate systems are used for storing video data and device data, then each system can be optimized for its specific data type, but temporal synchronization and data compliance become difficult to achieve
Solution Approach 1:
The patent merges video data and device data into a single unified storage system. The signal processing device combines video frames with embedded device data, measurement data, and timing information into one integrated data structure that is stored together. This eliminates the need for separate storage systems and ensures temporal synchronization is built into the data structure itself, resolving the contradiction between reliability of synchronization and complexity of integration.
Solution Approach 2:
The signal processing device acts as an intermediary between the video camera and device data sources. It receives video data from the camera and device data from various medical devices, processes them into a synchronized format, and stores the combined data. This intermediary role allows different data sources to maintain their optimization while achieving reliable temporal alignment through the coordinating signal processing device.
2Measurement precision
If precise synchronization of electrical data with video frames is attempted, then temporal alignment can be achieved, but the complexity and effort required for synchronization increases significantly
Solution Approach 1:
The system performs preliminary synchronization actions by embedding timing information and device data directly into the video data stream at the source. The signal processing device captures device data and video frames simultaneously and pre-aligns them before storage, eliminating the need for complex post-processing synchronization. This preliminary action achieves precise temporal alignment without the high effort required for real-time or post-hoc synchronization.
Solution Approach 2:
The patent changes the parameter of data storage format to accommodate synchronized multi-source data. Instead of storing video and device data separately with external timing references, the system transforms the data structure to embed device data and timing information directly within the video data container. This parameter change simplifies synchronization by making temporal alignment an inherent property of the stored data rather than a complex processing requirement.
3Loss of information
If all additional information is stored with video data, then complete documentation is achieved, but storage requirements and data management complexity increase
Solution Approach 1:
The patent segments the additional information into distinct data categories (device data, measurement data, timing information) and embeds them in structured segments within the video data stream. Each segment contains specific metadata about the corresponding video frame or time period. This segmentation allows complete documentation to be maintained while organizing data in a manageable structure that reduces unnecessary storage overhead compared to storing all data in raw, unstructured formats.
4Productivity
If dynamic measurement data changing during frame duration is recorded, then time-critical process evaluation is enabled, but the complexity of recording and evaluation increases
Solution Approach 1:
The signal processing device continuously captures and processes device data and video data throughout the entire procedure without interruption. The system maintains continuous synchronization and embedding of device data into video frames as they are captured, ensuring that time-critical dynamic measurement data is recorded in real-time. This continuous action enables efficient post-procedure evaluation while avoiding the complexity of batch processing or retrospective synchronization that would be required if data were recorded separately.
