Dear Sir/Madam,

My name is Ahmad Nobah, I am a medical physicist working in the field of radiotherapy and the initiator of the international radiotherapy plan competition and the Radiation Knowledge initiative, which aims at sharing the best planning skills for better radiotherapy plan qualities.

In 2016, we have initiated an international radiotherapy plan competition, it was a success story, as close to 400 planners participated from 55 countries worldwide. This competition was followed by knowledge sharing live-webinars per TPS, presented by the top score planners, to share their thinking methodologies. The videos are shared on our YoutTube channel, which has reached 4150 views so far.

2017 International Radiotherapy Plan Competition

In 2017, we have started a new initiative called Radiation Knowledge, which is a cloud base platform that aims at improving the quality and sharing the practical knowledge of all applications in radiation in medical field. We have started with radiotherapy planning, and gradually we will go to other fields.

Help Us in Spreading The Word

We would like to invite the French Society of Medical Physics to share this competition with the  medical physics society members to join us in this knowledge sharing event and register in our 2017 international plan competition through our website

In the 2016 Plan competition, French physicists have proved to be the best, the first and fifth rank were from France, As can be seen from our 2016 website. Also France was the largest country in Europe participating in our event, we are so happy to have more French physicists with us :)

Kindly find the banner of our competition attached to this email.

Thank you for your time

Kindest Regards,
