Witryna23 mar 2024 · Computed tomography (CT), also known as, especially in the older literature and textbooks, computerized axial tomography (CAT), is an imaging modality that uses x -rays to build cross-sectional images ("slices") of the body. Cross-sections are reconstructed from measurements of attenuation coefficients of x-ray beams passing … Witrynao Reduces radiation dose in proportion to the increase in pitch (UNLESS scanner automatically increases mA with increase in pitch as Siemens and Philips multidetector CT scanners do). o But, may increase slice sensitivity profile, creating larger effective slice thickness and reducing z-axis resolution.
