Apparatus and method pertaining to dynamic use of a radiation therapy collimator
First Claim
1. A method for use in administering radiation therapy to a target volume of a patient using a radiation-therapy beam and differing angles of exposure in conjunction with a multileaf collimator, comprising:
- at a radiation-therapy treatment-facilitation platform;
providing treatment-plan information regarding a plurality of different angles of exposure to employ when administering the radiation therapy to the target volume;
using the treatment-plan information to determine corresponding, and differing, aperture configurations for a second collimator that is disposed between a source for the radiation-therapy beam and the multileaf collimator to be dynamically used when administering the radiation therapy for at least some of the differing angles of exposure.

Abstract
A radiation-therapy treatment-facilitation platform (200) provides (101) treatment-plan information regarding a plurality of different angles of exposure to employ when administering radiation therapy to a given target volume (203). This treatment-plan information is then used (103) to determine corresponding, and differing, aperture configuration for a second collimator (207) that is disposed between a source (201) for the radiation-therapy beam (202) and a multileaf collimator (206). By one approach, this second collimator is dynamically used when administering the radiation therapy for at least some of the differing angles of exposure. These teachings will optionally accommodate also providing (102) form information regarding the target volume that is used, along with the aforementioned treatment-plan information, to determine the aperture settings for the second collimator.

15. An apparatus for use in administering radiation therapy to a target volume of a patient using a radiation-therapy beam and differing angles of exposure in conjunction with a multileaf collimator, comprising:
-
a first memory having treatment-plan information regarding a plurality of different angles of exposure to employ when administering the radiation therapy to the target volume stored therein; a processor operably coupled to the first memory and being configured to use the treatment-plan information to determine corresponding, and differing, aperture configurations for a second collimator that is disposed between a source for the radiation-therapy beam and the multileaf collimator and that is to be dynamically used when administering the radiation therapy for at least some of the differing angles of exposure. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
