Abstract
Embodiments of the invention provide systems and methods for generating combined image data representing a volumetric image of a subject and a color textured external surface of the subject. According to one embodiment, two-dimensional image data and volumetric data of a subject is obtained using it two-dimensional imager and a volumetric scanner, respectively. The two-dimensional image data represent color texture of the subject, and the volumetric data represents both an internal and external structure of the subject. An opacity threshold of the volumetric data is set to render an external surface of the subject without generating external surface mesh data. An array ray is extended from a view point of the two-dimensional image data to the external surface of the subject such that the external surface of the subject has an opacity level higher than the opacity threshold. The two-dimensional image data is mapped to the external surface of the subject based on the extended array ray, and combined image data comprising the two-dimensional image data and the volumetric data is generated.
