1. A method of adapting a treatment plan, the method comprising:
- preparing a treatment plan for a patient for treating a patient condition, the preparation including acquiring an internal reference image of the patient;
acquiring three-dimensional internal images of the patient in substantially a treatment position;
performing deformable registration of the images;
acquiring data relating to a radiation dose delivered to the patient;
applying a biological model to relate the radiation dose delivered and a patient effect; and
adapting subsequent dose delivery of the treatment plan in a radiation delivery device based on the deformable registration and the biological model.

Abstract
A system and method of adapting a radiation therapy treatment plan. The method includes the acts of preparing a treatment plan for a patient, acquiring images of the patient, performing deformable registration of the images, acquiring data relating to a radiation dose delivered to the patient, applying a biological model relating the radiation dose delivered and a patient effect, and adapting the radiation therapy treatment plan based on the deformable registration and the biological model.

18. A computer program embodied by a computer readable medium capable of being executed by a computer, the computer program for use in a treatment system, the computer program comprising:
-
a treatment plan module operable to generate a treatment plan for a patient, the plan based at least in part on an internal reference image of the patient; an image acquisition module operable to acquire a three-dimensional internal image of at least a portion of the patient in substantially a treatment position; a deformation module operable to generate a deformable registration between the reference image and the acquired image; and a modeling module operable to relate a radiation dose delivered to the patient and an effect of the radiation dose on the patient and to adapt subsequent dose delivery of the treatment plan based on the deformable registration and a biological model.
