Segmented Shielding Chamber for Radiotherapy Radiation Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiation therapy devices require dedicated machine rooms for radiation shielding, which increases construction costs and limits their application due to the need for extensive shielding to protect operators and others from radiation exposure.
Innovation Solution
A shielding apparatus comprising shielding shell segments that form a shielding chamber around the radiation device, reducing the need for a dedicated machine room by partially or fully shielding radiation, allowing the device to be placed in any location while maintaining safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a radiation device is placed in a dedicated machine room with sufficient radiation shielding, then the safety of operators and other people is ensured, but the construction cost increases and the application is limited
Solution Approach 1:
The shielding system is divided into a movable shielding component integrated with the radiation device and a stationary shielding structure. The movable shielding component moves with the radiation device, providing portable protection, while the stationary structure provides fixed protection when the device is in use, eliminating the need for a fully enclosed dedicated machine room
Solution Approach 2:
The shielding system transitions from a static enclosed machine room to a dynamic configuration where the movable shielding component can follow and protect the radiation device during movement, while the stationary shielding structure provides protection at operational positions
2Reliability
If extensive radiation shielding is provided to protect operators and others, then safety is improved, but the device complexity and space requirements increase
Solution Approach 1:
The shielding system is segmented into movable and stationary components, each serving specific protection functions. The movable shielding component integrates with the radiation device, while the stationary structure provides fixed protection, reducing overall system complexity compared to a fully enclosed machine room
Solution Approach 2:
The movable shielding component serves multiple functions: it provides radiation protection during device movement, acts as part of the shielding system when the device is operational, and can be repositioned or removed as needed, reducing the need for complex dedicated shielding structures
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The shielding apparatus effectively reduces the requirements for radiation shielding, lowers construction costs, and expands the application scenarios of radiation therapy devices by enabling them to be used in various settings without the need for a dedicated machine room, while also alleviating patient claustrophobia by increasing available space.
Implementation Method 1
the shielding chamber at least partially shields the scattered radiation generated by the radiation device
Data Source
AI summary
A shielding apparatus is provided. The shielding apparatus includes: at least one shielding shell segment, the at least one shielding shell segment constituting a shielding chamber, the shielding chamber being arranged on a periphery of a radiation device and shielding radiation generated by the radiation device. The shielding chamber is arranged on the periphery of the radiation device, and the shielding chamber at least partially shields scattering radiation generated by the radiation device, which can thus reduce the requirements of the radiation device for radiation shielding of a dedicated machine room or get rid of the dependence of the radiotherapy device on a dedicated machine room.
