'''CT''' ( '''''computed tomography''''' ) is a diagnostic method where we measure '''the intensity of a narrow beam of''' [[X-ray radiation - mechanism of formation|X-ray radiation]] that has passed through the patient's body in different directions. 

'''The computer calculates the image''' from the measured values .

The radiation source is gradually rotated 180° around the patient's body at small angles, so that each incision is irradiated from many directions. The computer then calculates '''the absorption values at a certain point of the transmittance plane''' and displays the values in a certain color or brightness on the display.

The radiation detectors in CT equipment are '''very sensitive''' and distinguish '''a large number of radiation intensities''' , i.e. the image is better.
