Development of wireless personal dosimeters for the protection of medical staff and patients in interventional radiology procedures
This proposal is built on the expertise acquired, in the past few years, on detector R&D, remote data transfer and the use of the Timepix and Dosepix technologies for dosimetry, by CERN Radiation Protection Group (HSE-RP-SP and HSE-RP-DC sections) with the support of the EP-ESE-ME section, the Erlangen Centre for Astroparticle Physics (ECAP), Germany, and the Institut de Radiophysique (IRA) in Lausanne. The scope of this proposal is to develop two versions of Dosepix-based dosimeters with real-time data acquisition and transfer: one version for whole-body dosimetry and one for eye lens dosimetry, the latter specifically conceived for the protection of medical staff during interventional radiological procedures.
The dosimeter will also be designed to be able to operate in pulsed fields to be used for example at Flash radiation therapy (RT) facilities, the latest cancer treatment modality currently being introduced in the clinical practice.
The hybrid pixel detectors of the Medipix family (including Dosepix) are CERN technologies. W-MON is a project currently ongoing in the Special Projects section of CERN Radiation Protection group (HSE-RP-SP), to develop a distributed network of interconnected silicon sensors to monitor radioactivity in waste containers. An extensive expertise has been built in the domain of wireless data transfer, miniaturization, reduction in power consumption and integration into an Internet of Things (IoT) infrastructure.
