Disposable Radiochemistry Device for Thermoluminescent Dose Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing radiolabelled compounds, such as PET tracers, lack a reliable way to measure the actual number of doses synthesized, leading to customers paying fixed prices that may not reflect the actual usage, and there is a need for a method to accurately determine the amount of radiolabelled compounds produced.
Innovation Solution
Incorporating radiation-sensitive materials, such as thermoluminescence (TL) materials, into disposable radiochemistry devices to record the radiation dose, allowing for the measurement of the actual amount of radiolabelled compounds produced, enabling charging based on the number of doses rather than the number of devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If disposable devices are sold at a fixed price, then manufacturing and distribution is simplified, but customers pay for unused capacity leading to inefficiency
Solution Approach 1:
The patent replaces manual radiation measurement methods with automated radiation sensors that continuously monitor and record radiation levels throughout the synthesis process. This automated system calculates the actual number of doses produced, enabling pay-per-use pricing that matches customers only for the doses they receive, eliminating waste of unused radiolabelled compound capacity.
2Measurement precision
If radiation sensors are integrated into the disposable device, then accurate dose measurement is enabled, but device complexity increases
Solution Approach 1:
The patent incorporates radiation sensors directly into the disposable device, which is then discarded after a single use. This approach enables accurate radiation dose measurement and automatic calculation of doses produced, while avoiding the need for complex reusable measurement systems. The disposable nature of the device makes the added sensor complexity acceptable and cost-effective.
3Measurement precision
If the number of radiation-sensitive materials is increased, then measurement accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses radiation-sensitive materials that record radiation exposure as a measurable signal, creating a permanent record of the radiation doses produced during synthesis. This recorded data can be read and processed to calculate the exact number of doses, providing accurate measurement without requiring multiple redundant sensing systems.
