Solution Overview

Problem

Existing quality assurance (QA) tools for energy-based treatment plans, particularly Flash energy treatment plans, are inadequate and difficult to employ, leading to inaccurate dose delivery that can result in insufficient radiation for treatment or excessive harm to healthy tissue.

Innovation Solution

A control circuit optimizes an energy treatment plan and determines a quality assurance dose rate metric by comparing delivered dose rates with threshold values, providing a simple and intuitive metric to ensure accurate dose delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing QA tools are used for Flash energy treatment plans, then the treatment plan can be verified, but the tools are inadequate and difficult to employ leading to inaccurate dose delivery

Engineering Contradiction:
Improvedose delivery accuracyVSAvoidQA tool usability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent extracts the essential QA verification function from complex existing QA tools and implements it through a simple dose rate metric calculation. The system separates the critical verification function (comparing delivered dose rate to threshold values) from the complexity of traditional QA tooling, making QA accessible while maintaining reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces complex, expensive QA tools with a simple, easily implementable dose rate metric system. The verification mechanism uses basic computational resources to calculate and compare dose rates against threshold values, providing effective QA verification without requiring sophisticated equipment or complex software systems.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Reliability

If energy is applied to treat target volume, then therapeutic effect is achieved, but adjacent tissues and organs receive excessive radiation causing harm

Engineering Contradiction:
Improvetreatment efficacyVSAvoidcollateral damage to healthy tissue
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements feedback by continuously monitoring the delivered dose rate and comparing it against pre-established threshold values. The system provides real-time verification that the radiation delivery matches the treatment plan specifications, enabling immediate detection and correction of deviations that could cause either insufficient treatment or excessive collateral damage.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent uses parameter changes by establishing and enforcing specific dose rate threshold values as critical parameters. By monitoring whether delivered dose rates exceed these thresholds, the system dynamically controls radiation delivery to ensure therapeutic effectiveness while preventing excessive radiation to healthy tissues, adapting the verification process to the specific treatment requirements.

Inventive Principle:
Principle #35Parameter changes

AI summary

A control circuit optimizes an energy treatment plan (such as, but not limited to, a Flash energy treatment plan) to therapeutically treat a given patient's treatment volume with energy to provide an optimized energy treatment plan. The control circuit determines at least one delivered dose rate as regards applying the energy pursuant to the optimized energy treatment plan and then determines a quality assurance dose rate metric that corresponds to that at least one delivered dose rate. The control circuit then informs a user regarding information that corresponds to the quality assurance dose rate metric.
