The process of creating a cross-sectional tomographic plane of the body by rotating an x-ray tube around the body part is called

• A. Cat Scan
• B. Ultrasound
• C. Radiography
• D. Fluoroscopy

Answer: (A)

Rotating the X-ray tube around the body part to create cross-sectional slices is computed tomography, often called a cat scan. In this method, the tube and detectors circle the patient, gathering X-ray data from many angles. A computer reconstructs those multiple projections into detailed cross-sectional images—or slices—that reveal internal structures at specific depths. This rotational, tomographic approach gives a three-dimensional view of the area, which is why it’s distinct from flat 2D radiographs. Ultrasound uses sound waves instead of X-rays and doesn’t produce cross-sectional CT-like slices. Radiography provides a single flat image from one or a few angles, not a reconstructed slice. Fluoroscopy offers real-time X-ray video, not the static cross-sectional images CT generates.
