E!11654, ENEFRF, Energy Efficient PET Cancer Diagnostics: Novel RF Source for Radioisotope Production
|Coordinator||Comheat Microwave AB|
|Funding from Vinnova||SEK 4 999 021|
|Project duration||November 2017 - August 2022|
Purpose and goal
The purpose of the project was to gather expertise in the high-power RF area to develop the next generation of RF generators based on new semiconductor technology for isotope-producing cyclotrons for PET (Positron Emission Tomografi). The goal was to reduce system cost and energy consumption compared to today´s electron tube-based RF generators for to make PET technology more available globally. Those goals were achieved during the project.
Expected results and effects
The project has resulted in a 27MHz RF generator with 20kW output that can be integrated with a commercially available cyclotron. Two patents have been generated and formed the basis for the development of a first prototype for a 100MHz/10kW system. Furthermore, progress has been made with the development of a new 200V LDMOS-halvledare for high-power applications in the RF area. The project has also led to the graduation of a doctor at Uppsala University and three master theses. We expect to upgrade PET technology globally with continued development and business cooperation.
Planned approach and implementation
Different expertise among the participants in the field of RF is complemented each other well and made the work efficient and successful. The joint knowledge ranged from semiconductors, amplifiers, systems and manufacturing know-how to knowledge of the application. We have worked methodically with risk mitigation and requirements specification and have therefore been able to reprioritize in time, which has been successful in reaching our objective. The know-how and knowledge developed during the project could be used to generate more R&D activity for all partners involved.
