Solution Overview
Problem
Current tumor resection planning techniques face challenges due to the complexity of organs like the liver, where precise planning is hindered by the subjectivity of interpreting 2D medical imaging and the lack of interaction and collaboration among surgeons.
Innovation Solution
A mixed reality tumor resection planning tool that integrates advanced visualization, interactive segmentation, risk assessment, and collaborative features, allowing surgeons to navigate 3D datasets, segment structures, define risk margins, and simulate vessel clipping, all within a shared mixed reality environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If 2D medical imaging data is used for tumor resection planning, then the planning process is simple and accessible, but the spatial relationship interpretation is subjective and imprecise
Solution Approach 1:
The patent transforms 2D medical imaging data into immersive 3D virtual reality representations, allowing surgeons to visualize anatomical structures and tumor locations in three dimensions. This dimensional transformation enables accurate spatial relationship interpretation while maintaining accessibility through standard VR headsets and computing hardware.
Solution Approach 2:
The system creates a digital copy of the patient's anatomy by rendering 3D models from 2D CT or MRI scan data. These virtual copies preserve all spatial relationships and anatomical details, allowing surgeons to interact with and measure the tumor environment without risking patient safety during the planning phase.
2Ease of operation
If conventional 2D planning methods are used, then the planning process is quick to implement, but collaboration and interaction among surgeons are limited
Solution Approach 1:
The patent introduces a shared virtual reality environment as an intermediary platform where multiple surgeons can simultaneously access and interact with the same tumor data. This virtual space serves as a common ground for collaboration, allowing team members to discuss surgical approaches, mark tumor boundaries, and plan resections together in real-time or asynchronously.
Solution Approach 2:
The system enables surgeons to perform preliminary planning actions in the virtual environment before the actual surgery. Multiple surgeons can pre-mark tumor boundaries, plan resection margins, and simulate surgical approaches during the planning phase, reducing the need for complex intraoperative decision-making and minimizing surgical time.
3Manufacturing precision
If detailed 3D visualization is implemented, then surgical planning accuracy is improved, but the complexity of the planning tool increases
Solution Approach 1:
The patent replaces complex mechanical or manual 3D reconstruction methods with automated computer-generated rendering. The system automatically generates accurate 3D visualizations from standard 2D medical imaging data using algorithms that preserve spatial relationships, eliminating the need for manual modeling while achieving high precision.
Solution Approach 2:
The virtual reality planning tool serves multiple functions within a single system: it provides 3D visualization, enables measurement and marking of tumor boundaries, facilitates collaboration among surgeons, and allows simulation of surgical approaches. This multi-functionality reduces the need for multiple separate tools while maintaining comprehensive planning capabilities.
