SYSTEM AND METHOD FOR PATIENT SETUP FOR RADIOTHERAPY TREATMENT

摘要

The invention comprises a method and apparatus for determining an adjustment to be applied to a radiation treatment plan. A radiation treatment plan, comprising a plurality of treatment parameters including at least the position of the patient and external and internal anatomical features of a patient, is first obtained. After this the visual representation of at least one external feature of the patient in reference to a first reference coordinate system is obtained. At substantially the same time as the external feature visual representation is obtained a visual representation of at least one internal anatomical feature of the patient in a second reference coordinate system is obtained. Finally the visual representations are compared with the original radiation treatment plan and adjustments are made based on the visual representations.
