AVM Image Superimposition With Transparency-Aligned MRI and MRA
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical personnel face challenges in aligning and analyzing T2 MRI and TOF MRA images for AVM detection, leading to deviations in treatment planning due to the lack of consistent alignment and separate presentation of these images, which affects the quality of treatment.
Innovation Solution
A superimposing images analysis system that aligns and superimposes TOF MRA and T2 MRI images, allowing transparency adjustment and ROI marking, with optional tissue segmentation and dose recommendation for accurate determination of lesion, CSF, and brain tissue regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If T2 MRI and TOF MRA images are obtained through different wave sequences and imaging principles, then the images provide different symptom information, but the images cannot be aligned consistently and require separate viewing windows
Solution Approach 1:
The patent merges T2 MRI images and TOF MRA images into a single aligned view by superimposing the MRA image onto the MRI image. This allows medical personnel to simultaneously observe both vascular structures and tissue characteristics in one window, eliminating the need to switch between separate image browsers while preserving all symptom information from both imaging modalities.
2Measurement precision
If T2 MRI and TOF MRA images are viewed separately in different windows, then each image can be analyzed independently, but alignment consistency is lost and time is wasted switching between images
Solution Approach 1:
The system combines multiple images into a single aligned display by superimposing TOF MRA images onto T2 MRI images with consistent spatial registration. This eliminates position alignment errors between separate views and allows medical personnel to compare vascular and tissue information simultaneously without time-consuming switching operations.
Solution Approach 2:
The patent adds a transparency dimension to the image display by allowing adjustable transparency of the superimposed MRA image. This enables medical personnel to selectively emphasize either vascular structures or tissue characteristics by adjusting transparency levels, providing an additional control dimension for optimal image analysis while maintaining precise spatial alignment.
3Loss of information
If the marked AVM region contains CSF region and brain tissue region in addition to lesion vessel region, then comprehensive tissue distribution information is obtained, but manual tissue division and analysis time increases
Solution Approach 1:
The patent combines T2 MRI images (which provide excellent soft tissue contrast for distinguishing CSF, brain tissue, and lesion regions) with TOF MRA images (which highlight vascular structures) into a single aligned view. This allows medical personnel to simultaneously analyze all tissue distributions and vascular structures without separate manual segmentation processes, reducing analysis time while preserving comprehensive tissue information.

AI summary
A superimposing images analysis system for AVM includes an image capturing unit, an image superimposing and aligning unit, and a transparency adjustment unit. The image superimposing and aligning unit is connected to the image capturing unit, and the transparency adjustment unit is connected to the image superimposing and aligning unit. The image capturing unit captures a brain MRA image and a brain MRI image. The image superimposing and aligning unit receives the brain MRA image and brain MRI image from the image capturing unit, and performs superimposing and aligning with the received images to generate a superimposing brain image. The transparency adjustment unit adjusts the transparency of the brain MRA image or the brain MRI image in the superimposing brain image according to a transparency adjustment instruction so as to generate a compared superimposing brain image.
