What kind of views does a computed tomography scan generate using computer assistance?

• A. Ultrasound
• B. A computer
• C. A Magnetic field
• D. A radioactive tracer

Answer: (B)

Computed tomography creates cross-sectional views of the body by using computer reconstruction of X-ray data. As the X-ray source and detectors rotate around the patient, the system collects attenuation information and the computer processes these measurements with algorithms to produce digital images that represent thin slices. These views can be displayed in axial planes and reformatted into coronal or sagittal planes, or rendered in 3D. This computer-assisted reconstruction is what gives CT its detailed internal images. Other imaging methods use different principles—ultrasound relies on sound waves, MRI uses magnetic fields and radiofrequency signals, and nuclear imaging uses radioactive tracers.
