Which imaging modalities use an x-ray tube?

• A. Mammography
• B. Fluoroscopy
• C. Computed Tomography CT
• D. All of the above

Answer: (D)

X-ray tubes are the source of ionizing radiation used in many imaging methods. They produce x-rays by accelerating electrons toward a metal target, and the resulting photons create images on detectors or film as they pass through the body. Mammography relies on a dedicated x-ray tube to generate the low-energy x-rays that best visualize breast tissue, with compression and filtering optimized for that exam. Fluoroscopy uses an x-ray tube to provide a real-time beam, allowing dynamic imaging as contrast moves or as the patient or a physician performs a procedure. Computed tomography uses a rotating x-ray tube around the patient to capture many angles, which are then reconstructed into cross-sectional images. Because all three modalities use an x-ray tube to generate the imaging photons, the correct answer is all of the above.
