Which of the following modalities utilizes ionizing radiation and relies on differences in photon attenuation coefficients of various tissues to generate cross-sectional grayscale images?
- A.Magnetic Resonance Imaging
- B.Computed TomographyCorrect answer
- C.Ultrasonography
- D.Thermography
Solution
Computed Tomography (CT) uses X-rays (ionizing radiation) and measures the attenuation of X-ray beams as they pass through different tissues, reconstructing them into cross-sectional images based on Hounsfield units.
