Medical Record Timeline Interface for Patient History Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical information display systems are inadequate for retrieving and visualizing a patient's comprehensive medical history, including past diseases and treatments, as they primarily focus on specific body regions and lack the ability to display information from different regions or treatment histories effectively.
Innovation Solution
A medical information display apparatus and method that utilize a timeline interface to retrieve and display electronic medical records, superimpose marks on an external human body image to represent examined regions, and provide gradation-based importance indicators for each region, allowing users to easily identify and access detailed information on past treatments and diseases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user interface displays medical information by selecting a region on a human body shape or image, then medical images related to the selected region can be extracted and displayed, but it is impossible to obtain information about diseases in different regions or past treatment histories
Solution Approach 1:
The patent introduces a timeline dimension to the traditional spatial region-based selection interface. By adding the time axis, users can now select not only regions but also time periods to retrieve medical information. This dimensional expansion enables access to both spatial (region-based) and temporal (time-based) medical records, resolving the contradiction between ease of region selection and loss of historical information.
Solution Approach 2:
The user interface is designed to handle multiple types of queries simultaneously - both region-based selection and time-based selection. The same interface can retrieve medical images for a selected region at a specific time, or retrieve all medical information for a patient across different time periods. This multi-functionality ensures that neither regional nor historical information is lost.
2Ease of operation
If a touch-panel interface generates a coronal image sliced at a generated base line, then image switching is enabled, but it is impossible to check what kind of image is present besides the selected image
Solution Approach 1:
The patent adds a temporal dimension to image navigation. Instead of only switching between spatial images (axial, coronal, sagittal views), the interface now enables users to navigate through time by selecting time periods on the timeline. This allows users to see not only the currently selected image but also access historical images from different time points, resolving the contradiction between ease of image switching and loss of information about other present images.
3Measurement precision
If medical information is displayed as a list for a selected region, then region-specific information can be retrieved, but comprehensive patient history including past diseases and treatments from different regions cannot be obtained
Solution Approach 1:
The interface dynamically adapts its behavior based on user input. When a user selects a region, the system retrieves region-specific information with precision. When a user selects a time period, the system retrieves comprehensive historical information. The system can also combine both selections to get region-specific information at specific time points. This dynamic adaptability ensures both precise region-specific retrieval and comprehensive historical access.
Solution Approach 2:
The patent segments medical information retrieval into independent dimensional components: spatial segmentation (by region) and temporal segmentation (by time period). Users can selectively combine these segments according to their needs - viewing region-specific information, time-specific information, or both simultaneously. This segmentation approach maintains precision for region-specific queries while enabling versatility for comprehensive historical retrieval.
Data Source
AI summary
A predetermined period is selected on timeline, and electronic medical record information about examination and treatment received by a predetermined person to be examined during the selected period is retrieved. All of examined regions recorded in the electronic medical record information are extracted therefrom. Further, external view image representing an external view of the person to be examined is displayed, and marks representing the examined regions are superimposed at the positions of the examined regions in the external view image.
