Systems conformation beam

The proton beam is shaped using mechanical systems installed along the beam line. At the end of the beam line, a telescopic nozzle is used to attach the custom accessories for your treatment:

  • The collimator enables to protect healthy tissues located on the side of your tumor. Each collimator is unique, machined according to the shape of your lesion. It is a unique accessory, identified and checked for each patient.

  • The compensator enables to adjust the depth of penetration of protons in each point of your tumor. It is a unique accessory, identified and checked for each patient. This accessory is not used for ophthalmological treatments where it is replaced, if necessary, by a plexiglas filter. Other beam shaping options enable to perform tumor location scanning, either in a plane or in a volume. Such options are particularly interesting for the treatment of complex tumoral volumes.
