Rotating Phantom Support for Radiation Measurement Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In particle beam therapy systems with a rotating gantry, the installation of radiation measurement instruments at varying positions of the irradiation port is time-consuming and labor-intensive.
Innovation Solution
A radiation-measurement-instrument support device with a cylindrical casing that houses phantoms and radiation measurement instruments, supported by a base that allows the casing to rotate and fix at arbitrary angles, facilitating easy alignment with the irradiation port.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a phantom and radiation measurement instrument are fixed to the irradiation port using an attachment, then radiation measurement can be performed, but it takes time and effort to fix the instruments
Solution Approach 1:
The support device enables dynamic positioning of the radiation measurement instrument through rotation around the irradiation port. The instrument can be moved to different angular positions and fixed at arbitrary angles, allowing flexible measurement configurations without time-consuming manual attachment procedures.
Solution Approach 2:
The support device serves multiple functions: it holds the radiation measurement instrument, enables rotational movement around the irradiation port, and provides positioning at arbitrary angles. This multi-functional design replaces multiple separate attachment operations with a single versatile device.
2Adaptability or versatility
If the irradiation port rotates to different positions for treating different patient sites, then versatile treatment is enabled, but the measurement instrument must be repositioned each time
Solution Approach 1:
The support device is designed to rotate dynamically around the irradiation port, allowing the measurement instrument to follow the port to different treatment positions. This dynamic capability maintains measurement readiness regardless of the irradiation port's angular position.
Solution Approach 2:
The support device automatically adapts to different irradiation port positions through its rotational mechanism. The device can be repositioned to match the new treatment angle without requiring complex manual intervention or complete reattachment procedures.
