Dear colleagues,

Thank you for your previous interest in the online webinars organized by the IAEA Radiation Protection of Patients Unit (RPOP).

We would like to invite you to join us for our next webinar, which will be held online on Thursday, 1st September 2022, at 11 am CEST (Vienna time) in English.

Estimation of organ doses from internal and external exposures in health physics depends on computational models of the human body (phantoms), and Monte Carlo calculations ─ two tools that have seen drastic advancement recently.  Phantoms have evolved from simple stylized phantoms to more accurate voxel phantoms based on personal anatomical images to re-create the human body in 3D digital form. Using the latest deep-learning image segmentation tools involving convolutional neural networks, patient-specific phantoms can be created in a few minutes ready for Monte Carlo calculations of organ doses.

In the meanwhile, ‘near real-time’ Monte Carlo simulation, based on graphics processing unit (GPU), can reduce organ dose computing time from hours to less than several seconds. - These technological advances suggest that radiation protection dosimetry may be ready to shift from the ICRP “Reference Man” paradigm that has been based on population-average anatomical and physiological assumptions for the past 60 years, to person-specific organ dosimetry. This webinar will cover these major computational tools for radiation protection dosimetry and discuss future directions.
  

We look forward to seeing you.
