Virtual 4D treatment suite
First Claim
1. A method comprising:
- identifying relative motion between a region of interest of a patient and at least a portion of a treatment field defined by a proposed treatment plan;
calculating an expected therapy dose and an associated temporal variation in the expected therapy dose to be delivered to the region of interest for the proposed treatment plan based on the identified relative motion between the region of interest and the at least the portion of the treatment field; and
determining whether to apply a dose management technique to the proposed treatment plan based on the expected therapy dose and the associated temporal variation in the expected therapy dose.

Abstract
A virtual 4D treatment suite includes a dose calculation module, a gating module, and a dose rate adjustment module. The 4D treatment suite may be used to virtually analyze the impact the motion of a target tissue has on therapy for a particular patient and a proposed treatment plan. For example, for a proposed treatment plan, the dose calculation module may calculate a dose that would be received by a target tissue and an associated dose temporal variation based on an identified movement of the target tissue relative to at least a portion of a treatment field. Based on the calculated expected therapy dose and dose temporal variation, the gating module may determine whether to implement a gating technique for the proposed treatment plan and/or the dose rate adjustment module may determine whether to adjust the dose rate of the proposed treatment plan.

11. A system comprising:
-
a dose calculation module that calculates an expected therapy dose and an associated temporal variation in the expected therapy dose to be delivered to a region of interest for a proposed radiation therapy treatment plan for a patient based on an identified relative motion between the region of interest and at least a portion of a treatment field; and a dose management module that determines whether to implement a dose management technique based on the expected therapy dose and the associated temporal variation in the expected therapy dose. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
