DETECTORS AND ACCELERATORS APPLIED TO MEDICINE IFIC i i i i i h i i i i f PARTNER

  • IFIC is participating in the training activity of PARTNER

students offering a one week course on “Detectors and Accelerators for Medicine”.

  • The course will be also open to other European graduate

students interested in Medical Physics.

  • The PARTNER course will take place at the beginning of

June 2009 at IFIC- Valencia, just before the planned IFIMED’09 W k h i t d t t ti l f th IFIMED’09 Workshop oriented to potential users of the Facility.

  • The course will consist of five different topics developed

in four hours each, plus six hours for tutorial sessions.

Accelerators for Medicine Accelerators for Medicine Accelerators for Medicine Accelerators for Medicine

This course will provided an introduction of the most used Accelerators in Medicine. We will introduce the concept, Accelerators in Medicine. We will introduce the concept, general description of the most important parameters for linear accelerators, cyclotrons and synchrotrons. We will introduce the special case of the use of these accelerators in p Medicine, and more specifically in Hadrontherapy. Finally we will review the novel concepts in the field of Medical Accelerators. The course will be organized in four lectures of one hour each, complemented with tutorials where we could compare the different kinds
