- W4367305114 abstract "X-ray computed tomography, commonly having an acronym of CT, is useful to obtain cross sectional images of the region of interest, based on the attenuation of X-rays from those areas. The normal 512 x 512 pixels of the CT images denote the CT number generally defined in terms of Hounsfield units. The linear attenuation coefficient values obtained are in terms of the values relative to that of water, magnified to a larger value by multiplying the normalized difference by a larger integer, called the CT number. The simplest approach in CT is to obtain multiple scans of the region of interest using circular rotations of source and detectors. In this regard, if Nyquist criterion is satisfied, then a complete 3-dimensional dataset can be obtained. Radiation dose to the subjects in CT is about 100 times greater than that in conventional radiography." @default.
