In the context of imaging, "3D ultrasound" refers to a technique that captures multiple two-dimensional images and synthesizes them to create a three-dimensional representation of the structures being examined. This process involves acquiring multiple slices of data from various angles and then reconstructing those slices to visualize the anatomy in three dimensions.

This capability allows healthcare professionals to gain a more comprehensive understanding of complex structures, such as organs or tumors, as they can appreciate depth and spatial relationships that are not visible in standard 2D sonography. The enhanced visualization provided by 3D images can be crucial in prenatal imaging, assessing anatomical anomalies, and in procedural guidance.

Other options do not accurately describe 3D ultrasound. For instance, capturing a single 2D image pertains to standard ultrasound techniques and does not convey the three-dimensional aspect. Showing only outlines of structures is limiting and does not represent the full capabilities of 3D imaging, which provides detailed information about the volume and contour of the anatomy. Lastly, the method that focuses solely on measuring sound wave frequencies relates more to Doppler ultrasound rather than 3D imaging techniques, which prioritize structural visualization instead.
