Final answer:
The actual attenuation data measured by the detectors from all projections during a scan is contained in CT image data. Computed Tomography (CT) is a medical imaging technique that uses computers to analyze several cross-sectional X-rays to produce highly detailed images. The relative absorption of the X-rays along different directions is computer analyzed to create a two-dimensional view of the scanned area, which can then be further processed to obtain three-dimensional information.
