Computer Analysis
Experimentation with monochromatic imagery (black and white) revealed the potential of exploiting the hundreds of shades of grey available in this medium. The next step would be to digitally manipulate the greyscale to enhance the acquisition of usable information. The first applications of this new technology would be by the intelligence community and by medical researchers who would refine and further develop the technology, resulting in the introduction of the CAT Scan.
Another technology introduced roughly at this time would be that of the echo-cardiogram, which could show heart movements and the actual blood-flow through its chambers.
One of the more recent developments has been that of magnetic resonance imaging (MRI), where tissue and blood-flow anomalies could be detected. Evidence of spinal cord injuries and even complex neurochemical reactions in the brain could now be detected and documented. Scientists have also explored the possibilities of multi-spectral imaging such as the 1970s LandSat, and yet more parts of the electromagnetic spectrum such as astronomical gamma-ray imaging.

Famous quotes containing the words computer and/or analysis:
“The archetype of all humans, their ideal image, is the computer, once it has liberated itself from its creator, man. The computer is the essence of the human being. In the computer, man reaches his completion.”
—Friedrich Dürrenmatt (1921–1990)
“... the big courageous acts of life are those one never hears of and only suspects from having been through like experience. It takes real courage to do battle in the unspectacular task. We always listen for the applause of our co-workers. He is courageous who plods on, unlettered and unknown.... In the last analysis it is this courage, developing between man and his limitations, that brings success.”
—Alice Foote MacDougall (1867–1945)
