Medical Image Labeling via Vertebral Interpolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical image processing methods struggle to detect and label vertebral bodies and intervertebral disks, especially in unclear X-ray images, as they are not designed to handle images with unclear or compressed anatomical structures.
Innovation Solution
A medical image processing apparatus that includes a processor for detecting vertebral bodies and intervertebral disks, labeling detected parts, and interpolating missing parts based on predetermined conditions, using an interpolator to enhance labeling accuracy even in unclear images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional detection methods are used on clear MRI images, then labeling accuracy is improved, but detection reliability deteriorates when images are unclear or compressed
Solution Approach 1:
The system changes the parameter of image clarity by processing unclear images through interpolation to generate clearer versions, allowing the detection algorithm to work on multiple parameter states of the same image data
Solution Approach 2:
The system performs preliminary interpolation to generate candidate vertebral body positions before executing the detection algorithm, preparing the data in advance to ensure reliable detection even when original images are unclear
2Adaptability or versatility
If detection is performed on unclear X-ray images, then processing versatility is improved, but measurement precision deteriorates due to unclear vertebral bodies
Solution Approach 1:
The system changes the clarity parameter of X-ray images through interpolation processing, transforming unclear original images into clearer candidate images that maintain the same anatomical information but with enhanced detectability
Solution Approach 2:
The system introduces an intermediary interpolation process between the original unclear image and the detection algorithm, creating intermediate candidate images that serve as a bridge to improve measurement precision without losing versatility
3Productivity
If conventional labeling is executed on compressed intervertebral disks, then processing speed is improved, but detection reliability deteriorates as disks become undetectable
Solution Approach 1:
The system performs preliminary interpolation to predict and mark the positions of compressed intervertebral disks before detection, proactively addressing the reliability issue without adding significant processing time during the main detection phase
Solution Approach 2:
The system changes the positional information parameter by calculating candidate positions based on adjacent vertebral bodies, transforming the undetectable compressed disk information into detectable positional data

AI summary
A medical image processing apparatus includes a memory; and at least one processor configured to execute detecting one or more vertebral bodies and one or more intervertebral disks in a medical image; labeling each part satisfying a predetermined condition among the one or more vertebral bodies and the one or more intervertebral disks detected by the detecting; interpolating a vertebral body or an intervertebral disk in a case where the one or more vertebral bodies and the one or more intervertebral disks detected by the detecting do not include the vertebral body or the intervertebral disk that satisfies the predetermined condition; and executing the labeling also for the vertebral body or the intervertebral disk interpolated by the interpolating.
