Medical Image Display Apparatus with Automatic View Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radiotherapy planning workstations require extensive user interactions to find optimal views of anatomical structures in medical images, especially when images are taken in unusual positions, making it difficult for users to efficiently review and delineate anatomical features.
Innovation Solution
An image display apparatus that uses a template generation method to determine display parameters based on anatomical features and their significance values, allowing for automatic adjustment of image views to minimize deviations from predefined positions and orientations, ensuring anatomical features are displayed consistently and effectively, regardless of the image's original orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual browsing of image slices is used to find anatomical structures, then the user can locate structures of interest, but the time required for review and delineation increases significantly
Solution Approach 1:
The system automatically performs the task of locating and displaying anatomical structures without requiring manual user intervention. The automatic view determination system analyzes the image data set and autonomously selects optimal viewing parameters and displays relevant anatomical structures, making the system serve itself rather than requiring continuous user guidance.
Solution Approach 2:
The system pre-calculates and prepares optimal viewing parameters and anatomical structure locations before the user needs them. By automatically determining the most relevant views and structures in advance, the system eliminates the need for users to manually browse through multiple slices to find what they need.
2Reliability
If images are displayed in their original unusual orientations, then the original image data is preserved, but the usability and review efficiency deteriorates
Solution Approach 1:
The system applies different display transformations to different regions or aspects of the image data. While the original image data remains intact, the system selectively reorients and displays specific anatomical structures in optimal viewing orientations, allowing each structure to be presented in its most useful view while preserving the integrity of the source data.
Solution Approach 2:
The system dynamically adjusts display parameters including orientation, rotation, and viewing angles based on the detected anatomical structures. Rather than using fixed display orientations, the system adapts the presentation of image data to match the actual anatomical content, improving usability while maintaining data fidelity.
3Adaptability or versatility
If multiple manual interactions are required to reformat volumetric images, then precise control over view parameters is achieved, but the complexity of the operation increases
Solution Approach 1:
The system automatically determines optimal viewing parameters including reformatting angles, slice orientations, and display configurations without requiring manual user input. The automatic view determination system performs what would otherwise require multiple interactive adjustments, significantly simplifying the user interface while maintaining adaptability to different anatomical scenarios.
Solution Approach 2:
The system introduces an automatic view determination module that acts as an intermediary between the raw image data and the final display. This intermediary automatically translates volumetric image data into optimally formatted views, eliminating the need for users to manually perform multiple formatting operations while preserving precise control over the final display parameters.
4Productivity
If automatic view determination is implemented, then user interaction is reduced, but the need for accurate anatomical feature detection increases
Solution Approach 1:
The system replaces manual visual inspection and manual adjustment mechanisms with automated computational methods. Advanced image processing algorithms and anatomical feature detection systems automatically identify and locate anatomical structures, substituting the mechanical process of manual browsing and adjustment with automated digital analysis that can detect features more accurately and efficiently.

AI summary
The invention relates to an image display apparatus for displaying an image like a three-dimensional medical image of an object. A template providing unit (3) provides a template defining display parameters for displaying the image based on anatomical features of the object, and an anatomical feature detecting unit (4) detects an anatomical feature in the image. A display parameter determining unit (5) determines a display parameter defining, for example, a desired view, based on the detected anatomical feature and the template, and a display unit (8) displays the image by displaying, for example, the desired view, in accordance with the determined display parameter. This allows the image display apparatus to show the image on the display in a desired usual way as defined by the template, even if in the originally provided image the object is shown in an unusual way.
