Computerized tomography,evices and a computer. The first units were produced in Britain by EMI Medical Ltd. in 1973 and were designed by G. N. Hounsfield. These units were slow and crude by modern standards and could only be used for scanning heads. The system was able to differentiate more efficiently than conventional ra

Computerized tomography,ow and crude by modern standards and could only be used for scanning heads. The system was able to differentiate more efficiently than conventional radiography between areas in the head with differing X-ray attenuation coefficients, these areas being displayed as shades of grey-scale on a television monitor.

Applied Scanning Probe Methods IIIan soft tissue (atomic number 7.4) or fat (atomic number 6.0). The image is formed by emergent primary radiation reaching the film. Contrast is determined partly by the extent to which primary radiation penetrates the various body structures and partly by the effects of scatter.

https://doi.org/10.1007/978-1-4615-2770-1 imaging systems are dependent on the mains supply. With this in mind it would seem sensible and logical for us to start our studies by looking at the way in which electricity is generated at the power station and then distributed to users throughout the country.
