Hardware ROI Border Generation for Medical Imaging Lag Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical imaging systems face challenges in efficiently generating borders for regions of interest due to reduced memory and processing power, leading to lag and visual artifacts when using software graphics overlays.
Innovation Solution
The system allocates border values to pixels simultaneously with display values, eliminating the need for software graphics overlays and reducing lag by incorporating border information directly into the image data, allowing for real-time display of region of interest borders without graphic overlays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software graphics overlay is used to generate ROI border, then border can be displayed on image, but lag phenomenon occurs when user pans the ROI due to superimposition of data on stored video data
Solution Approach 1:
The patent merges the border generation process with the image display process by incorporating border values directly into the video data stream at the hardware level. This integration eliminates the separate software overlay step that causes lag, as the border is now generated simultaneously with the image data through hardware circuitry rather than post-processing software operations.
Solution Approach 2:
The patent replaces the software-based graphics overlay mechanism with a hardware-based border generation system. By using dedicated hardware circuits to generate and superimpose border values directly onto the video data stream, the system eliminates the processing delays inherent in software operations while maintaining accurate border display.
2Volume of moving object
If imaging systems are reduced in size, then portability is improved, but less area is available for large video graphics cards and additional memory for storing video data
Solution Approach 1:
The patent extracts the border generation function from complex software graphics processing and implements it through dedicated hardware circuits. This extraction eliminates the need for large video graphics cards and additional memory, as the border values are generated directly from the imaging data through specialized hardware rather than requiring general-purpose graphics processing resources.
Solution Approach 2:
The patent implements a localized hardware solution specifically for border generation within the imaging system. By adding dedicated border generation circuitry that operates directly on the imaging data stream, the system maintains sophisticated border display capabilities without requiring overall system expansion, thus preserving portability while enhancing local functionality.
Data Source
AI summary
A system and method for generating a border of a region of interest of an image, such as a medical image, are disclosed. Imaging data is acquired for generation of an image. A region of interest of the image is determined. A display value is allocated to a plurality of pixels, respectively, based on color or tissue information from the imaging data. If at least one pixel corresponds to a border of the region of interest, a border value is allocated to the at least one pixel substantially at the same time as when the display value is allocated. The image having the border of the region of interest is displayed.
