Abstract
Systems and methods for generating a movement model that requires less storage space than movement models of the prior art are disclosed. This movement model may be based on x-ray images of a patient and may be configured for estimating movement of organs within the patient during medical treatment. The movement model comprises at least two deformation fields associated with strong time points and a plurality of interpolation parameters associated with weak time points. In contrast with the prior art, the stored movement model does not include deformation fields associated with all time points. Because interpolation parameters rather than deformation fields are associated with the weak time points, the movement model requires less storage than movement models of the prior art. The stored movement model is optionally used to calculate interpolation fields that can be used to model movement of a patient.
