Medical procedures where real-time X-ray imaging is needed have rapidly increased in number in the past decades. Consequently, the personnel dosimetry for medical staff has become more important, also in light of the revision of worker safety regulations. Detailed knowledge of the dose-rate is needed to reduce the total absorbed dose during a single procedure. Real-time monitoring through wearable active devices would greatly facilitate this task. In this work, we will present the characterization of the RAPID wireless device (based on CMOS imager as X-ray sensing detector) in clinical conditions, with PMMA phantoms. The prototype has shown the capability to measure dose-rates with a frequency in the range of few Hz, and an uncertainty smaller than 10%.

Abstract
Medical procedures where real-time X-ray imaging is needed have rapidly increased in number in the past decades. Consequently, the personnel dosimetry for medical staff has become more important, also in light of the revision of worker safety regulations. Detailed knowledge of the dose-rate is needed to reduce the total absorbed dose during a single procedure. Real-time monitoring through wearable active devices would greatly facilitate this task. In this work, we will present the characterization of the RAPID wireless device (based on CMOS imager as X-ray sensing detector) in clinical conditions, with PMMA phantoms. The prototype has shown the capability to measure dose-rates with a frequency in the range of few Hz, and an uncertainty smaller than 10%.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
