To so alogaritmi, ki jih pretvori računalnik v digitalne podatke, da na koncu sestavi fantomsko sliko skeniranega dela telesa.
Malce razlage v angleščini:
Computed tomography (CT) involves complex processing of digital data by using mathematical principles called reconstruction kernels. Scan data are based on penetration and attenuation measurements of photons as they traverse matter. This raw data must then be converted to digital data and displayed as a CT image. The multi-slice CT scanner refers to a special CT system equipped with a multiple-row detector array to simultaneously collect data at different slice locations. In CT, selection of a CT convolution kernel determines the trade-off between image sharpness and pixel noise |
