Spinal Alignment via 3D Model Posture Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical imaging technologies face inaccuracies when comparing two-dimensional images across different patient postures, leading to potential over- or under-correction during spinal surgeries, which can result in poor surgical outcomes and patient dissatisfaction.
Innovation Solution
The method involves generating three-dimensional models from preoperative and intraoperative images, comparing these models to determine posture differences, and providing suggested motions to align the patient's spine more accurately with the preoperative plan, using artificial intelligence and image processing techniques to improve spinal alignment and surgical planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two-dimensional images are used for comparing preoperative and intraoperative spine images, then the imaging process is simple and quick, but the alignment accuracy deteriorates due to posture variations
Solution Approach 1:
The patent transforms two-dimensional images into three-dimensional models of the spine. By creating 3D representations from 2D preoperative and intraoperative images, the system enables accurate comparison of spinal alignment while accounting for posture variations. The 3D models allow for precise measurement of vertebral positions and orientations regardless of the patient's positioning during surgery.
2Measurement precision
If 3D models are generated and compared to determine posture differences, then spinal alignment accuracy is improved, but the processing time and computational resources increase
Solution Approach 1:
The system generates three-dimensional spinal models from preoperative images before the surgical procedure begins. This preliminary creation of 3D models allows for pre-planning of spinal alignment corrections. During intraoperative imaging, the system compares the new 3D model with the preoperative model to quickly determine posture differences and guide surgical adjustments, reducing intraoperative decision-making time.
Solution Approach 2:
The patent replaces manual measurement and comparison methods with automated image processing algorithms and artificial intelligence. The system automatically generates 3D models, compares them across different time points, and calculates posture differences without requiring manual intervention, significantly reducing processing time despite the complexity of 3D analysis.
3Reliability
If manual comparison of images is performed, then the process is straightforward, but the reliability of surgical planning deteriorates due to human error
Solution Approach 1:
The system replaces manual image comparison performed by surgeons with automated computer-based image processing algorithms. The automated system consistently compares preoperative and intraoperative 3D models, calculates posture differences, and provides surgical guidance without human fatigue or subjective interpretation errors, enhancing the reliability of surgical planning.
Solution Approach 2:
The system provides continuous feedback by comparing intraoperative 3D models with preoperative plans and real-time surgical measurements. This feedback loop allows surgeons to immediately see the effects of surgical maneuvers on spinal alignment and make adjustments accordingly, improving the reliability of achieving the desired surgical outcome.
