Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radiation therapy devices cannot integrate stereotactic multi-source focused radiation therapy with conformal and intensity-modulated radiation therapy, limiting the ability to provide different treatment options for various tumors.
Innovation Solution
A radiation treatment plan generation method and system that utilize a radiotherapy equipment with at least two therapeutic heads, including a focused therapeutic head and a conformal therapeutic head, to determine the most suitable therapeutic approach and drive approach for irradiating the tumor, allowing for synchronous or asynchronous treatment to optimize treatment efficiency and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single radiation therapy device uses only one therapeutic head (focused or conformal), then the device structure is simple and easy to operate, but it cannot provide both accurate multi-source focused therapy and conformal therapy for different tumor types
Solution Approach 1:
The patent combines a focused therapeutic head and a conformal therapeutic head into a single radiation therapy device. The focused therapeutic head implements multi-source focused radiation therapy for precise treatment, while the conformal therapeutic head implements intensity-modulated radiation therapy for conformal treatment. Both therapeutic heads are integrated on one device to provide multiple treatment options without requiring separate devices.
Solution Approach 2:
The radiation therapy device is designed with multi-functionality to handle different tumor types and treatment requirements. The focused therapeutic head is optimized for intracranial tumors or head and neck tumors requiring high-precision focused therapy, while the conformal therapeutic head is optimized for body tumors with complicated shapes or large sizes requiring conformal therapy. This universal design allows a single device to serve multiple therapeutic purposes.
2Adaptability or versatility
If multiple therapeutic heads are integrated on one device, then both focused therapy and conformal therapy can be provided, but the device complexity increases
Solution Approach 1:
The device is segmented into distinct functional modules: a focused therapeutic head for multi-source focused radiation therapy and a conformal therapeutic head for intensity-modulated radiation therapy. Each head is an independent functional unit with its own radiation sources and control systems, allowing them to operate separately or in combination depending on treatment requirements.
Solution Approach 2:
The device incorporates dynamic switching capability between different therapeutic heads and treatment modes. The system can dynamically select which therapeutic head to use based on the specific treatment requirements, tumor type, and clinical scenario, providing flexibility despite the increased structural complexity of having multiple heads.

AI summary
The present disclosure discloses a radiation treatment plan generation method, which is applied to a therapeutic equipment comprising at least two therapeutic heads. The method comprises the steps of: acquiring images of an area of the patient with a tumor; determining a treatment target region including the tumor as a region for being irradiated with a radiation beam upon radiotherapy; obtaining a prescription dose of the treatment target, wherein the prescription dose comprises a parameter of prescription dose value that is a magnitude of a dose received by the tumor; and determining a therapeutic head, a therapeutic approach and a therapeutic drive approach suitable for irradiating the target region, based on the therapeutic target region and the prescription dose thereof.
