Present and Future Developments in Radiotherapy Treatment Units.
Technical advances in the design of medical accelerators are making possible the exploration of new treatment techniques. Technology currently available to the radiation oncologist allows the use of internal and dynamic wedges. Multileaf collimators can be used for static treatment ports, and dynamic field shaping and beam modulation using multileaf collimators has been shown to be feasible. Computer interfaces are necessary to transfer the complex treatment sequences that are possible with these devices. Such network interfaces also provide for more efficient conventional treatments. New machines such as X-band linear accelerators and advanced proton accelerators are being developed for applications such as boron neutron capture therapy and proton conformal therapy.
