Acquisition and Applications

Both industrial and medical CT:– Utilize the differential attenuation (intensity
decrease) of X-rays– Attenuation is a function of density and atomic
number
Industrial differs from medical CT:– Sample rotates between source and detector– Higher energy X-rays– Longer acquisition times– Smaller X-ray focal spots + more densely
packed detectors
