1. A method for determining an adjustment to be applied to a radiation treatment plan, the method comprising the steps of:
- obtaining a radiation treatment plan comprising a plurality of treatment parameters including at least the position of a patient and external and internal anatomical features of the patient;
obtaining a visual representation of at least one external feature of the patient in reference to a first reference coordinate system;
at substantially the same time as the external-feature visual representation is obtained, obtaining a visual representation of at least one internal anatomical feature of the patient in reference to a second reference coordinate system; and
determining the adjustment based on the visual representations.

Abstract
Positioning an anatomical feature of a patient during repeated radiotherapy treatments, and accounting for variations in that position between treatments allow a patient to be placed in a substantially repeatable orientation with respect to a treatment device.

21. A system for determining an adjustment to be applied to a radiation treatment plan, the system comprising:
-
storage for storing; a plurality of parameters including at least the position of a patient and external and internal anatomical features of the patient; a representation of at least one external feature of the patient in reference to a first reference coordinate system; and a representation of at least one internal anatomical feature of the patient in reference to a second reference coordinate system, and a positioning module in communication with the storage for adjusting, based on the visual representations, one or more of the parameters to compensate for changes in the position of the patient with respect to the at least one patient internal feature. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method for determining a radiation treatment plan, the method comprising the steps of:
-
obtaining a visual representation of at least one external feature of a patient with respect to a reference coordinate system; at substantially the same time as the external-feature visual representation is obtained, obtaining a visual representation of at least one internal anatomical feature of the patient with respect to the reference coordinate system; and determining a radiation treatment plan comprising a plurality of treatment parameters in the reference coordinate system based on the position of the patient relative to the external and internal anatomical features in the reference coordinate system. - View Dependent Claims (32, 33)
