Multi-Head Radiotherapy Gantry for Focused and Conformal Therapy
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 their ability to provide both accurate multi-source focused therapy and conformal therapy in a single device for different or the same tumors.
Innovation Solution
A radiotherapeutic system with a gantry and at least two therapeutic heads, including a focused multi-source head and a conformal intensity-modulated head, along with a driving control method that allows the gantry to rotate 360 degrees and the therapeutic heads to move along radial and axial directions, enabling synergistic therapy by combining both treatment modalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single radiation therapy device uses only one therapeutic head (either focused multi-source or conformal IMRT), then the device structure is simple and easy to operate, but it cannot provide both focused therapy and conformal therapy for different tumor types
Solution Approach 1:
The radiation therapy device is designed with multiple therapeutic heads (focused multi-source therapeutic head and conformal IMRT therapeutic head) mounted on a single gantry, enabling the device to perform both stereotactic focused radiation therapy and conformal intensity-modulated radiation therapy. This multi-functional design allows one device to serve multiple therapeutic purposes for different tumor types and treatment requirements.
Solution Approach 2:
The therapeutic function is segmented into separate therapeutic heads, each specialized for a specific therapy type. The focused multi-source therapeutic head is dedicated to stereotactic focused radiation therapy, while the conformal IMRT therapeutic head is dedicated to conformal intensity-modulated radiation therapy. This segmentation allows each head to be optimized for its specific function while being integrated into a unified device platform.
2Adaptability or versatility
If a single radiation therapy device integrates multiple therapeutic heads for both focused and conformal therapy, then therapy versatility is improved, but the device complexity increases
Solution Approach 1:
Multiple therapeutic heads are merged onto a single gantry structure, sharing common support infrastructure, positioning systems, and control mechanisms. The focused multi-source therapeutic head and conformal IMRT therapeutic head are both mounted on the same gantry, allowing them to share the rotational mechanism and positioning systems, thereby reducing overall device complexity compared to having separate devices.
3Productivity
If only one type of radiation therapy is performed per treatment session, then the treatment process is simple and fast, but the therapy efficiency and treatment quality are limited
Solution Approach 1:
The device incorporates dynamic switching capability between different therapeutic heads and therapy modes. The control system can dynamically select and switch between the focused multi-source therapeutic head and the conformal IMRT therapeutic head based on treatment requirements, allowing flexible adaptation to different clinical scenarios and enabling complex treatment plans to be executed efficiently in a single session.
