Sampling Geometries of the beam: The sampling
geometry of the beam in CT scanners along the different generations can be
described as three configurations: Further advances: Another limiting factor in

Further advances: Another limiting factor
in image acquisition was tungsten alloy X-ray tube. The need for long, high intensity
exposures and very stable output placed enormous demands on both the tube and
generator (power supply). Very high performance rotating anode tubes were
developed to keep up with demand for faster imaging, as were the regulated 150
kV switched mode power supplies to drive them. Modern systems have power
ratings up to 100 kW.
