DESCRIPTION:Speakers: OLIVERA CIRAJ BJELAC (IAEA\, AUSTRIA)\, PAULA TOROI 
 (STUK\,RADIATION AND NUCLEAR SAFETY AUTHORITY\, FINLAND)\, MICHELANGELO BI
 ONDI (USL TOSCANA SUD-EST\, ITALY)\, JONAS ANDERSSON (UMEA UNIVERSITY HOSP
 ITAL\, SWEDEN)\, OMAR MOHAMED NOOR (KING FAISAL SPECIALIST HOSPITAL AND RE
 SEARCH CENTRE\, SAUDI ARABIA) ()\nConsistent and reliable dosimetry in med
 ical X ray imaging depends on well defined calibration and measurement pro
 cedures\, making their critical assessment and harmonisation essential to 
 ensure traceable and comparable results across laboratories and clinical p
 ractice. Building on earlier CCRI webinars addressing challenges and recen
 t updates in X ray imaging dosimetry\, this third webinar focuses on advan
 ces in the calibration of X ray multimeters (XMMs) used in medical imaging
 . The webinar will address calibration approaches for key quantities measu
 red by XMMs beyond air kerma\, including tube voltage\, irradiation time\,
  and half value layer (HVL). In addition\, approaches for validating metro
 logical traceability and providing supporting evidence for these calibrati
 on services will be discussed.\n\n1. Education and training of radiation m
 etrologist: Olivera CIRAJ BJELAC\, IAEA and Marco ESPOSITO\, ICTP\n. Intro
 duction of ICTP university of Trieste Master of Advanced Studies in Medica
 l Physics and Radiation Metrology\n\n2. Air kerma and irradiation time: Mi
 loš ŽIVANOVIĆ\, VINS\, Serbia\n. What changes when the calibrated item 
 is XMM instead of an ionization chamber?\n· How should we define the irra
 diation time and how to obtain the reference value for it?\n\n3. Tube volt
 age: Stefan POJTINGER\, PTB\, Germany\n· How to obtain a reference value 
 for practical peak voltage (PPV)?\n\n4. HVL: Aino TIETÄVÄINEN\, STUK\, F
 inland\n· How to measure reference HVL value and estimate the uncertainty
 ?\n\n5. Conclusions: Paula TOROI\, STUK\, Finland\n· The future of X-ray 
 imaging dosimetry\n \nThe webinar is chaired by Massimo PINTO (ENEA\, Ital
 y)\n\nRegister:  bipm-org.zoom.us/meeting/register/BkJU6yZpRXaV_lGaLHwCUg\
