A __________ is a tomographic imaging technique that generates cross-sectional images of the anatomy in the axial plane.

Explanation:
Tomography creates cross-sectional views by focusing on a single plane while reducing the appearance of structures outside that plane. Computed tomography achieves this by rotating an X-ray source and detectors around the patient and using computer reconstruction to produce thin cross-sectional images in the axial plane. These axial slices run horizontally through the body and can be stacked to form a 3D representation, and they can also be reformatted into other planes if needed. This combination of rotating X-ray data and axial-plane reconstruction is what makes computed tomography the classic tomographic technique for obtaining cross-sectional anatomy. Fluoroscopy provides real-time 2D projections, PET emphasizes metabolic function, and MRI, while also producing cross-sectional images, is not defined by the same rapid axial tomographic reconstruction from X-ray attenuation.
