摘要：
A system and method includes acquisition of first surface data of a patient in a first pose using a first imaging modality, acquisition of second surface data of the patient in a second pose using a second imaging modality, combination of the first surface data and the second surface data to generate combined surface data, for each point of the combined surface data, determination of a weight associated with the first surface data and a weight associated with the second surface data, detection of a plurality of anatomical landmarks based on the first surface data, initialization of a first polygon mesh by aligning a template polygon mesh to the combined surface data based on the detected anatomical landmarks, deformation of the first polygon mesh based on the combined surface data, a trained parametric deformable model, and the determined weights, and storage of the deformed first polygon mesh.
