3D Brain Image Reconstruction for Accurate TMS Head Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for positioning non-invasive brain treatment devices like TMS or rTMS are inefficient and cause patient discomfort due to the inability to quickly and accurately locate the corresponding brain areas outside the skull.
Innovation Solution
A method for creating brain images through proportional correction of 3D head images using CT, MRI, or ultrasound, involving initialization, reference model construction, region growth, and model post-processing steps, to enhance precision and efficiency in positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional positioning methods (10-20 system, anatomically guided positioning, or trial and error) are used to locate brain areas for TMS/rTMS treatment, then the treatment can be performed, but the patient experiences discomfort and the process is time-consuming
Solution Approach 1:
The patent creates a 3D brain image model that copies the patient's actual brain structure from medical imaging data. This digital model allows doctors to visualize and locate target brain areas externally on the scalp surface corresponding to internal brain structures, eliminating the need for trial-and-error positioning and reducing patient discomfort while maintaining treatment accuracy.
Solution Approach 2:
The patent transforms 2D medical imaging data into a 3D visual model that displays both the skull surface and underlying brain structures in three dimensions. This dimensional transformation allows simultaneous visualization of external scalp landmarks and internal brain target areas, enabling accurate positioning without requiring the patient to undergo time-consuming trial positioning procedures.
2Productivity
If traditional positioning methods are used, then treatment can proceed, but medical resource consumption increases due to repeated adjustments and extended treatment time
Solution Approach 1:
The patent performs preliminary positioning using the 3D brain image model before the actual TMS/rTMS treatment begins. By pre-identifying and marking the exact scalp locations corresponding to target brain areas on the 3D model, the system eliminates the need for repeated adjustments during treatment, thereby reducing treatment time and medical resource consumption while improving overall productivity.
3Measurement precision
If doctors rely on inference from various images to locate brain areas, then treatment positioning can be attempted, but accuracy is insufficient and the process is complex
Solution Approach 1:
The patent merges multiple imaging modalities (CT, MRI, or ultrasound data) into a single integrated 3D brain image model that simultaneously displays the skull surface and underlying brain structures. This unified model correlates external scalp positions with internal brain target areas in one visualization, eliminating the need for doctors to mentally infer locations from separate images and significantly improving positioning accuracy while simplifying the overall process.
