Dosimetric Planning Consideration of Different High Energy Radiation Including Stereotaxy in Patients Receiving Radiotherapy

Abstract

Conformal radiotherapy requires the delivery of radiation beams that are tailored to the planning target volume. In practice, this is usually achieved using a CT study then positioning of the radiation beams in three dimensional space to match the beams to the target shape to minimize the treated volume and to keep doses to critical organs within acceptable limits. This process requires the use of blocked fields and non-coplanar beams.
