Cloud-Based Dose Verification for Multi-TPS Radiation Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic dose verification systems in radiation therapy are inadequate for verifying dose profiles produced by different Treatment Planning Systems (TPS) of various models or from different manufacturers, and they struggle to handle a high volume of verification requests from multiple hospitals or clinical facilities, leading to inconsistencies and increased workload for human verifiers.
Innovation Solution
A cloud-based system that includes a file service, a dose engine service, and a dose evaluation service to receive and parse DICOM files, determine secondary radiation dose profiles, and verify the accuracy of primary dose profiles using a consistency metric, enabling multi-tenant access and simultaneous processing of multiple requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current automatic dose verification systems are used, then dose verification can be performed, but they cannot verify dose profiles from different TPS systems of various models or manufacturers and struggle to handle high volume of verification requests
Solution Approach 1:
The cloud-based verification platform is designed to universally accept and verify dose profiles from multiple TPS systems and manufacturers through standardized interfaces and cloud processing, enabling one system to serve multiple purposes across different radiation therapy platforms
Solution Approach 2:
A cloud-based intermediary service is introduced between the TPS systems and verification processes, acting as a mediator that receives dose profiles from various TPS systems, processes them through standardized algorithms, and returns verification results, thereby enabling compatibility without requiring direct integration with each system
2Ease of operation
If manual verification by human verifiers is used, then flexibility in verification can be maintained, but workload increases and human error may occur
Solution Approach 1:
The system enables self-service verification where the cloud platform automatically processes verification requests, applies verification algorithms, and returns results without requiring manual intervention for routine verifications, while still allowing human oversight when needed
Solution Approach 2:
Manual mechanical verification processes are replaced with automated cloud-based computational verification systems that use algorithms to automatically compare dose profiles against verification criteria, eliminating repetitive manual tasks while maintaining verification accuracy
3Adaptability or versatility
If multiple hospitals or clinical facilities submit verification requests simultaneously, then service coverage can be expanded, but system resources may be overwhelmed
Solution Approach 1:
The verification workload is segmented and distributed across multiple cloud servers and processing nodes, allowing simultaneous handling of requests from multiple hospitals and facilities without overloading a single system, thereby maintaining reliability while expanding service capacity

AI summary
Systems (500) and methods (700) for verifying a primary dose profile generated by a radiation machine using cloud-based services are disclosed. An exemplary system (500) can include a cloud (530,600) that provides cloud-based services, and a user interface (136) that enables multi-tenant access to the cloud-based services. A file service (610) can extract from a patient (501) DICOM file image information and information about a radiation machine. A dose engine service (620) can determine a secondary radiation dose profile by applying a dose algorithm (624) to the image and the radiation machine information. The applied dose algorithm (624) can be different from the dose algorithm used by the radiation machine to generate the primary dose profile. A dose evaluation service (630) can use the secondary radiation dose profile to verify accuracy of the primary dose profile based on a consistency indicator between the primary and secondary dose profiles.
