US Patent 9824492 Hollow object model visualization in medical images

Techniques for generating a hollow model from a medical image are disclosed herein. In an example, a hollow model may be created within a medical imaging visualization application through the generation of a mask of an interior space of a segmented anatomical structure, the extrusion of a shell mask from the mask of the interior space, and the generation of a visualization of the shell mask within the medical imaging visualization application. For example, the mask may be provided as a layer in the medical imaging visualization application, allowing a user to visualize the produced shell mask of the hollow model from the perspective of the medical imaging. In further examples, the hollow model generation techniques may be used with techniques for shell region modifications, variable shell thickness, multiple shell layer, and trimming of shell endpoints.
