Fundamental principle of ct may be summarized as - An image of an object may be reconstructed on the basis of the attenuation that occurs as x radiation is transmitted through it Detectors measure - The radiation that is transmitted through the pt. An image is reconstructed in the basis of the magnitude of X-ray attenuation that occurs at spatially distributed points within the pt General process of ct imaging imaging may be divided into several steps- - Data acquisition- measurement of t...
