WebbThere are several advantages over conventional CT. The major advantage is the fast acquisition time, which results in less need for sedation of the central nervous system. The imaging of moving structures is less blurry. As EBCT generates X-rays with an electron beam, the radiation exposure is decreased. Webb6 nov. 2024 · The three phase power generator is also within the gantry module. 5. The x-ray tube in a CT scanner is designed to produce a fan beam of x-rays that is approximately as wide as the body. 6. Tissue attenuation is measured over a large region from one position of the x-ray tube. 7.

WebbIn comparison with the first scans, contemporary ones can scan in a few hundred milliseconds, and reconstruct an image of 2,048×2,048 pixels from hundreds of spiral slices. Essential physics. CT is based on the principle that the density of the tissue passed through by the X-ray beam can be measured by calculation of the attenuation coefficient.
