In one embodiment, a method includes receiving treatment information relating to a treatment plan for proton- or ion-beam therapy intended to irradiate a target tissue; receiving machine-limitation information relating to one or more limitations of one or more machines involved in the proton- or ion-beam therapy; determining a time-optimized beam current for a proton or ion beam based on the treatment information and the machine-limitation information, wherein the time-optimized beam current minimizes the time required to deliver a required quantity of monitor units to one of a plurality of spots, wherein each of the plurality of spots is a particular area of the target tissue; and delivering the time-optimized beam current to the particular area.

Time optimized radiation treatment

In one embodiment of the invention, a method for irradiating a target is disclosed. A proton beam is generated using a cyclotron. A first information is provided to an energy selection system. An energy level for the protons is selected using an energy selection system based on the first information. The first information comprises a depth of said target. The proton beam is routed from the cyclotron through a beam transfer line to a scanning system. A second information is provided to the scanning system. The second information comprises a pair of transversal coordinates. The proton beam is guided to a location on the target determined by the second information using a magnet structure. The target is irradiated with the protons.

Proton irradiation using spot scanning

The present invention relates to an irradiation device for irradiating an irradiation object with heavy charged particles at an irradiation station, comprising a particle accelerator for providing a particle beam and a swivelling device for swivelling the particle beam impinging on the irradiation object, wherein the swivelling device comprises a carrier pivotable about an axis. In accordance with the invention, the irradiation device is characterized in that the particle accelerator is mounted on the pivotable carrier.
