Explanation:
Detailed explanation-1: -Cross-sections are reconstructed from measurements of attenuation coefficients of x-ray beams passing through the volume of the object studied. CT is based on the fundamental principle that the density of the tissue passed by the x-ray beam can be measured from the calculation of the attenuation coefficient.
Detailed explanation-2: -A CT scan, or computed tomography scan, sends radiation through the body. However, unlike a simple X-ray study, it offers a much higher level of detail, creating computerized, 360-degree views of the body’s structures. CT scans are fast and detailed. They take longer than X-rays but are still fast (about one minute).
