The imaging modality that generates images through computed axial tomography (CAT) is CT (Computed Tomography). This technique utilizes X-ray technology to create cross-sectional images of the body, which are then processed by a computer to generate detailed slices of anatomy.

CT scans are particularly useful for visualizing complex structures within the body, such as organs, blood vessels, and tissues, and they provide much more detailed information than standard X-ray imaging. This method allows for better diagnosis and treatment planning because it can reveal conditions such as tumors, internal bleeding, and fractures with greater clarity.

The other modalities mentioned, such as ultrasound, MRI, and X-ray, utilize different principles and technologies to create images. Ultrasound employs sound waves, MRI uses powerful magnets and radio waves, and traditional X-ray primarily captures two-dimensional images using ionizing radiation. Thus, CT is specifically defined by its ability to produce images using the computed axial tomography technique, which differentiates it from the other imaging methods listed.
