A member asked:

How can a ct scan actually work?

A doctor has provided 1 answer

Multiple projections: A ct cross-sectional image (slice) is reconstructed from a combination of xrays shot from multiple directions/projections; therefore, there is no overlap of body parts and much better contrast compares to traditional xray images..
