Much of today was spent listening to talks on Iterative Reconstruction in CT images. This is a complicated image processing technique used to improve the image whilst being able to lower dose. It was shown that a dose saving of 60% could be found whilst maintaining image quality. We also heard about other techniques for lowering doses to below 1mSV level including reducing the kV used to perform the examination.
During the lunch hour there was chance to look at the ~200 posters in a range of topics, including radiotherapy, diagnostic x-ray and phantom testing. There was also an interesting one on tagging rhino tusk with radioactive tracers to catch poachers.
It was then onto Radiological and nuclear event preparedness. Representatives from four countries gave their take on how to prepare for a nuclear or radiological event, as well as advice and guidance from the IAEA, IRPA and WHO. It brought to light that medical physicists are often seen by the public as neutral/ independent sources of information and expertise. This means in the event of a disaster such as Fukushima, we may be called to do a number of different tasks including monitoring, quantifying and communicating with the press or public. For this to happen successfully careful planning is needed and training undertaken to ensure we all know the roles we are to play, whilst staying flexible and able to fill gaps where they appear.
