Medical Data Analysis Software
- Reduces the risk of missing signs of major injuries by improving the quality of X-ray data analysis
- Improves quality by identifying trends and key data points with a rich array of graphs
Oxford Computer Consultants participated in the development of a Windows-based application for the analysis of data produced by Oxford Positron's Autograph Camera. The Windows-based software analyses images and provides quantification of the data without the need for any intermediate step or sample handling.
The technology of the camera and imaging
Autoradiography, the technology the camera uses, involves the
measurement and analysis of samples in the form of flat sheets
blotted with radioactive patterns that have been produced by
electrophoretic or chromatographic methods. The traditional method
of visualising these patterns is to place the samples in close
contact with X-ray films.
An alternative to film is a phosphor plate that is 'developed'
after exposure with a laser beam. The MICAD (Microchannel Array
Detector) developed by Oxford Positron improves on these two
techniques in terms of analysis time and sensitivity.
Dr Jeavons' invention of MICAD overcame problems of poor spatial
resolution or low count sensitivity from the Multi-Wire
Proportional Chamber (MWPC) when imaging two-dimensional biomedical
samples. With MICAD, it is possible to achieve 10 to 100 times
greater sensitivity than is possible with X-ray film or phosphor
storage screens.
The camera's pedigree
The camera is a direct, electronic radiation imager which replaces X-ray films for genetics research and biomedical analysis. It was developed by Dr Alan Jeavons at Oxford Positron Systems. The technology for the Autograph Camera is based on the Nobel Prize-winning Multi-Wire Proportional Chamber (MWPC) invented in 1968 at CERN by Dr Georges Charpak.
