Emerging Technology in Cancer Treatment: Radiotherapy Modalities
October 01, 2003
Dr. Hevezi has outlined someexciting new developments inthe field of radiation oncologyin his thorough review. Since its inception,radiation oncology has beengeographically based, ie, related to theradiation exposure of tumor vs normaltissue. It is therefore a logical extensionof new radiographic technologythat allows for more preciseplacement of radiation fields than everbefore. Further, as outlined by Dr.Hevezi, the development of treatmentplanning computers coupled to verificationcomputers on the liner acceleratoris associated with precise radiationdelivery that exploits the relativeradiation dose between the tumorand normal tissue, allowing higherdoses to be used without increasedtoxicity.
