Dear Friends and Colleagues,

As chairman of the Scientific Committee, I consider it a great privilege to be writing this letter of invitation to the up-coming 11th Biennial ESTRO Conference on Physics and Radiation Technology to be held in London between the 8th and 12th of May, 2011.
This scientific programme will provide an opportunity to present and discuss new achievements in radiotherapy physics and technology whilst also offering a package of high level educational lectures. We aim to capture the interest of clinicians by offering presentations with physics and technology which may have an immediate impact on clinical radiotherapy and should therefore be appealing for the clinicians who will be present for the GEC ESTRO conference and the International Oncology Forum.
