Brain Implant Placement Planning Using 3D Imaging Landmarks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implant placement methods for brain stimulation therapies, such as deep-brain stimulation, lack precision and efficacy due to variations in implantation location and brain network specifics, leading to inconsistent therapeutic outcomes.
Innovation Solution
A system that utilizes image data analysis to identify anatomical landmarks, positions implants like DBS devices relative to features like the anterior commissure and posterior commissure, and correlates implant pose with activation volumes to plan and execute precise therapeutic procedures, aided by surgical navigation systems and tracking technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional implantation methods are used, then the procedure can be performed with simpler equipment, but the implantation precision and therapeutic outcome are insufficient
Solution Approach 1:
The system performs pre-operative imaging (MRI, CT, PET) and creates a 3D model of the patient's brain anatomy before the actual implantation procedure. This preliminary action allows for precise planning of the optimal implantation trajectory and target location, which is then executed during surgery using the pre-planned parameters, thereby improving implantation precision without requiring complex real-time adjustments during the procedure
Solution Approach 2:
The system introduces an intermediary planning software that acts as a mediator between the imaging data and the surgical procedure. This software integrates multiple imaging modalities, creates 3D visualizations, and allows clinicians to plan the exact implantation path and target coordinates before surgery. This intermediary layer translates complex medical images into actionable surgical parameters, improving precision while keeping the actual surgical equipment relatively simple
2Measurement precision
If multiple imaging modalities are integrated for comprehensive analysis, then the planning accuracy is improved, but the data processing time and system complexity increase
Solution Approach 1:
The system performs all imaging data acquisition (MRI, CT, PET) and processing before the surgical procedure begins. The planning software integrates and analyzes all imaging modalities in advance to create a comprehensive 3D model and determine the optimal target location and implantation trajectory. This preliminary data processing ensures high measurement precision without causing delays during the actual surgical procedure, as all planning is completed beforehand
Solution Approach 2:
The system creates a virtual 3D copy of the patient's brain anatomy by integrating multiple imaging modalities. This digital replica allows for comprehensive analysis and precise target identification without requiring simultaneous access to all original imaging data during surgery. The virtual model serves as a simplified representation that captures all necessary anatomical information, reducing the time needed to reference and process actual imaging data during the procedure

AI summary
Disclosed is a system to plan and position an implant in a subject. The planned position may be based upon various features and structures identified in a group of subjects for a current subject. The implant may then be positioned in a selected position including a relative position and orientation of one or more electrodes on the implant which may be identified as an optimal position for the selected current subject.
