Method and apparatus for using a designated patient structure as an area to be masked from radiation
First Claim
1. An apparatus comprising:
- a control circuit configured to;
provide a user with an opportunity to designate a patient structure to be protected from radiation when the designated patient structure overlies a patient target volume in a particular radiation treatment angle, thereby providing a designated patient structure;
when optimizing a radiation-treatment plan with respect to the patient target volume, using the designated patient structure as an area to be masked from radiation by at least one multi-leaf collimator during administration of the radiation-treatment plan when the designated patient structure is positioned between the patient target volume and a source of radiation;
a radiation treatment platform operably coupled to the control circuit and configured to deliver the radiation-treatment plan as optimized to a patient.

Abstract
A control circuit provides a user with an opportunity to designate one or more patient structures for a particular patient that are to be protected from radiation. When optimizing a radiation-treatment plan for that patient, then, the control circuit uses the designated patient structure(s) as an area to be masked from radiation during administration of the radiation-treatment plan. By one approach the aforementioned opportunity to designate patient structures as being designated patient structures comprises providing the user with an opportunity to so designate patient structures via a display. The aforementioned masking can be accomplished as desired including by appropriate use of a multi-leaf collimator.
