Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiotherapy equipment is limited by generating only one type of radiation, which is inadequate for treating tumors of varying sizes and types, necessitating improved treatment planning systems to adapt different types of radiation beams for precise tumor targeting.
Innovation Solution
A treatment planning system that selects from multiple modes to produce treatment plans for various radiotherapy heads capable of generating different types of radiation beams, allowing for tailored treatment plans based on tumor size and type, and coordinates the operation of multiple heads to enhance precision and effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If radiotherapy equipment uses a single treatment head generating one type of radiation, then the device complexity is reduced, but the adaptability to treat various tumor sizes and types deteriorates
Solution Approach 1:
The treatment planning system is designed to support multiple treatment heads (X-ray, electron, proton) within a single system, enabling one device to perform multiple radiation therapy functions. The system can adaptively select different treatment heads based on tumor characteristics, achieving universality without requiring separate dedicated equipment for each radiation type.
Solution Approach 2:
The system dynamically selects and configures appropriate treatment heads based on real-time treatment requirements, tumor size, and type. This dynamic adaptability allows the system to transition between different radiation modes (X-ray, electron, proton) as needed, rather than being fixed to a single radiation type.
2Adaptability or versatility
If radiotherapy equipment uses multiple treatment heads generating different types of radiation, then the adaptability to treat various tumors is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple treatment head control functions into a single integrated treatment planning system. By combining the planning and coordination of X-ray, electron, and proton treatment heads into one system, the patent reduces overall device complexity while maintaining the adaptability benefits of having multiple radiation types available.
3Manufacturing precision
If a single treatment plan is generated for one treatment head, then the manufacturing precision of the treatment plan is simplified, but the treatment efficacy for varying tumor types deteriorates
Solution Approach 1:
The system changes key parameters including radiation type (X-ray, electron, proton), energy levels, and beam configurations based on tumor characteristics. By dynamically adjusting these parameters according to tumor size, depth, and sensitivity, the system maintains high treatment plan precision while adapting to diverse tumor types.
