Lower-Limb CT Image Display Segmentation and Enlargement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CT image display systems require manual enlargement and repetitive movement to analyze long lower limb images, leading to increased time and effort for technicians to read and analyze blood vessel images.
Innovation Solution
A medical image display apparatus and method that divides a long lower-limb image into sections, allowing for adjustable enlargement and rotation, with a division boundary line, to facilitate easier viewing and reduce the need for manual enlargement and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the entire lower-limb image is displayed at original size, then the complete anatomical structure is visible, but the blood vessel details cannot be observed clearly
Solution Approach 1:
The display screen is divided into multiple regions: a first region displaying the entire lower-limb image and a second region displaying an enlarged portion of the image. This segmentation allows simultaneous viewing of both the complete anatomical structure and detailed blood vessel observations without requiring manual enlargement or movement between images.
2Measurement precision
If the image is enlarged to observe blood vessels, then the blood vessel details become visible, but the technician must repeatedly move between images
Solution Approach 1:
The display is segmented into multiple regions that can be simultaneously viewed. The first region shows the entire lower-limb image while the second region shows an enlarged view of a specific portion. This allows the technician to observe blood vessel details without repeatedly moving between separate images, significantly reducing image reading time.
Solution Approach 2:
The display system provides multiple functions simultaneously: it displays the complete lower-limb image, provides enlarged views of specific regions, shows division boundary lines, and allows adjustment of the enlarged region position. This multi-functionality eliminates the need for separate operations to view different aspects of the image.
3Measurement precision
If the image is divided into sections, then the blood vessel details become accessible, but the division boundary line may obscure the image continuity
Solution Approach 1:
A division boundary line is introduced as an intermediary element to separate the first region (entire image) from the second region (enlarged portion). The boundary line clearly indicates the transition between regions while maintaining the overall image structure, allowing the system to provide detailed views without obscuring the continuity of the anatomical structure.

AI summary
A medical image display apparatus and method, which divide a screen region into a first region whose length is relatively greater than a width thereof and on which an entire lower-limb image and a division boundary line dividing the lower-limb image in a widthwise direction, and a second region adjacent to the first region, and enlarge and display a part of the lower-limb image including the division boundary line on the second region. Thereby, it is possible to minimize work for image enlargement and repetitive movement in reading a computed tomography image and to reduce the reading time.
