What technique involves the construction of a 3D model by limiting displayed volumetric data?

The technique that involves the construction of a 3D model by limiting displayed volumetric data is surface rendering. This method primarily focuses on the outer surfaces of a structure, using specific thresholds to only visualize the outermost boundaries of the data set while excluding internal details. Surface rendering is beneficial in CT imaging for creating clear representations of anatomical structures, making it an excellent choice for various diagnostic applications such as visualizing bones or skin surfaces.

Shaded surface display, while related, often refers to the technique that emphasizes depth and lighting effects to enhance the visual appeal of the 3D model, but it is closely tied to surface rendering in terms of visual output. Temporal resolution pertains more to dynamic imaging and monitoring changes over time rather than constructing a static 3D model. Tube arcing is unrelated to 3D rendering; it refers instead to issues related to the X-ray tube and beam production.
