Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radiation therapy techniques require manual and time-consuming processes to generate optimal treatment plans, often resulting in varying field setups for similar patient cases, which can reduce operator confidence and familiarity with treatment plans.
Innovation Solution
The use of templates with proven radiation field setups based on tumor size, location, and patient geometry, allowing for personalized adjustments of static field positions using dose gradients and historical data to create trustworthy and optimized treatment plans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual field position setup optimization is performed, then treatment plan quality is improved, but time consumption and operator dependency increase
Solution Approach 1:
The patent applies preliminary action by pre-defining multiple field position templates with proven optimization for different tumor types and locations. These templates are prepared in advance and can be directly selected or slightly modified, eliminating the need for time-consuming manual optimization while maintaining high treatment plan quality.
Solution Approach 2:
The patent changes the parameter approach by transitioning from manual iterative adjustment of field positions to selecting from pre-optimized parameter sets (templates). Each template contains specific field positions, angles, and configurations that have been previously optimized, allowing rapid deployment without manual tuning.
2Productivity
If automatic field setup generation is used, then time consumption is reduced, but field setup variability and operator familiarity decrease
Solution Approach 1:
The patent applies copying by using proven field position templates that can be copied and adapted for similar cases. Instead of generating entirely new field setups, the system copies established templates and makes minimal patient-specific adjustments, ensuring consistency and operator familiarity while maintaining efficiency.
Solution Approach 2:
The patent achieves universality by creating templates that can serve multiple similar cases. A single template can be applied to various patients with similar tumor characteristics, providing consistent field setups across different cases while still allowing for necessary individualization.
3Reliability
If proven field templates are used, then operator confidence and familiarity increase, but personalization for specific patients decreases
Solution Approach 1:
The patent applies local quality by maintaining the overall structure and field positions from proven templates while allowing local modifications specific to each patient's anatomy and tumor characteristics. This enables operators to confidence in the proven framework while customizing critical patient-specific parameters.
Solution Approach 2:
The patent introduces dynamics by making the template system adaptable rather than rigid. Templates serve as dynamic starting points that can be adjusted based on patient-specific factors, combining the stability of proven configurations with the flexibility needed for personalization.

AI summary
Methods and systems are provided for developing radiation therapy treatment plans. A treatment template with radiation fields can be chosen for a patient based on a tumor location. Static radiation field positions can be adjusted for the patient, while arc radiation fields may remain the same. Static radiation field positions can be adjusted using dose gradient, historical patient data, and other techniques.
