Medical Image Display Device Abnormality Detection Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
With higher resolution modality acquiring three-dimensional images, the reduced interval between tomographic planes increases the number of images, leading to a risk that radiologists may overlook abnormalities, especially if the tomographic image with a CAD detection result is not displayed.
Innovation Solution
A medical image display device and method that includes controllers to display detection results, reference information, and notifications to ensure that all relevant images are reviewed, preventing the oversight of abnormalities by displaying the total number of detection results and their reference state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of tomographic images is increased to improve imaging resolution and reduce interval between planes, then imaging precision is improved, but the risk of overlooking abnormalities increases due to the large number of images requiring review
Solution Approach 1:
The system provides feedback to the radiologist by displaying the number of unreferenced detection results and notifying when abnormalities may have been overlooked. This feedback mechanism helps maintain reliability despite the increased number of images, as radiologists are alerted to potential missed abnormalities without needing to manually review every single image.
2Reliability
If all tomographic images are displayed for complete review, then diagnostic accuracy is improved, but the time and complexity of interpretation increases
Solution Approach 1:
The system extracts and highlights only the detection results marked by CAD from the large number of tomographic images. Instead of requiring review of all images, the system isolates and presents only the relevant detection results, significantly reducing interpretation time while maintaining diagnostic accuracy through targeted review of suspicious areas.
Solution Approach 2:
The system performs partial review by focusing on detection results rather than all images. The notification function provides excessive action by alerting radiologists to potential missed abnormalities, ensuring thorough review of critical areas without requiring complete manual inspection of every image in the series.
3Reliability
If CAD detection results are added to tomographic images, then abnormality detection capability is improved, but the complexity of image display increases
Solution Approach 1:
The system separates the detection result information from the full image display complexity by extracting only the essential detection result data. The notification function further simplifies this by presenting only critical information (number of unreferenced results) to the radiologist, reducing display complexity while maintaining abnormality detection capability.

AI summary
A first display controller displays a plurality of medical images in which a detection result of at least one abnormal part is added to at least one medical image, on a display. A second display controller displays a total number of detection results on the display. A third display controller displays reference information representing a reference state of the detection result on the display.
