What does CT stand for?

Explanation:
CT stands for Computed Tomography. It uses X-ray data taken from multiple angles around the body, and a computer reconstructs those data into cross-sectional images (slices). The term “computed” reflects this reconstruction process, turning raw projections into detailed pictures that help visualize different tissues based on density. This set apart from magnetic resonance imaging, which uses magnetic fields and radiofrequency energy; digital subtraction angiography, which highlights blood vessels with contrast and image subtraction; and positron emission tomography, which images metabolic activity using radioactive tracers often fused with CT for anatomy.
