Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cyclotrons for producing positron-emitting radioisotopes are costly, energy-intensive, and require extensive infrastructure, leading to inefficiencies in radiopharmaceutical production and distribution due to their large size, high energy consumption, and the short half-lives of these isotopes.

Engineering Contradiction Analysis
1Quantity of substance
If conventional cyclotrons are used to produce radioisotopes, then sufficient radioisotope quantity can be obtained, but the device size, energy consumption, and infrastructure requirements increase significantly
Solution Approach 1:
The patent divides the radioisotope production process into two independent segments: (1) a small micro-accelerator that produces a concentrated radioactive ion beam with sufficient specific activity, and (2) a separate radiochemical synthesis system that converts the radioactive ions into the desired radiopharmaceutical. This segmentation allows the accelerator to be much smaller while still producing adequate radioisotope quantities through high-specific-activity beam generation.
Solution Approach 2:
The invention changes the operational parameters of the accelerator by operating at lower beam power (1-10 kW range) compared to conventional cyclotrons, while compensating by optimizing the radioactive ion beam production efficiency and specific activity. This parameter change enables size reduction without sacrificing the fundamental capability to produce sufficient radioisotope quantities.
2Quantity of substance
If conventional cyclotrons are used to produce radioisotopes, then sufficient radioisotope quantity can be obtained, but the energy consumption increases significantly
Solution Approach 1:
The patent separates the high-energy beam generation function from the radiochemical synthesis function. The micro-accelerator operates at lower power (1-10 kW) to generate a concentrated radioactive ion beam, and the synthesis system completes the radiopharmaceutical production using much lower energy requirements, thereby dramatically reducing total energy consumption while maintaining adequate radioisotope production.
Solution Approach 2:
The invention changes the energy parameter by operating the accelerator in a low-power regime (1-10 kW) compared to conventional cyclotrons that consume tens to hundreds of kilowatts. The lower beam power is compensated by optimizing the radioactive ion beam production efficiency and specific activity, achieving sufficient radioisotope quantities with reduced energy input.
3Quantity of substance
If conventional cyclotrons are used to produce radioisotopes, then radioisotope production can be maintained, but the infrastructure requirements and costs increase
Solution Approach 1:
The patent divides the system into a compact micro-accelerator module and a modular radiochemical synthesis system. This segmentation allows the accelerator to be installed in smaller facilities without requiring the extensive infrastructure of conventional cyclotrons, while the synthesis system can be configured based on specific radiopharmaceutical production needs, reducing overall infrastructure complexity and cost.
4Weight of stationary object
If micro-accelerator with low beam power is used, then device size and energy consumption are reduced, but the radioisotope production quantity may be insufficient
Solution Approach 1:
The invention changes the operational parameters by optimizing the radioactive ion beam production at lower beam powers (1-10 kW). By adjusting parameters such as beam current, ion species selection, and target configuration, the system achieves sufficient radioisotope production quantities despite the reduced accelerator size and power capacity.
Solution Approach 2:
The patent concentrates the radioactive ion beam production to achieve high specific activity in a localized manner. Rather than distributing low-specific-activity radioisotopes throughout a large system, the micro-accelerator produces highly concentrated radioactive beams that can be efficiently converted into the desired radiopharmaceuticals, maintaining adequate production quantities with smaller device size.
