Which type of rendering is primarily utilized with three-dimensional echocardiography?

Comprehensive and Detailed Explanation From Exact Extract:

Three-dimensional echocardiography (3D echo) primarily uses volume rendering to provide a realistic and spatially accurate representation of cardiac structures. Volume rendering processes a full dataset of voxels (3D pixels) to produce detailed images, allowing clinicians to visualize complex anatomical relationships in real time.

Surface rendering is another technique but primarily used in post-processing to create a solid surface model; it is less used in live 3D echocardiography.

Planar and external rendering are not standard terms in 3D echocardiography.
