Here On Earth Video technology developed for use in space can sometimes find application here on Earth as well. British and American researchers have now presented two such examples. In the first case, a gamma ray camera originally used to record cosmic radiation is now used in diagnosing breast cancer. Patients suspected of having a tumor are injected with a faintly radioactive tracer, a liquid which prefers to settle in cancerous tissue. The gamma radiation camera is then capable of locating even tiniest secondary tumors by their radiation.
British astronomers plan to use the technology to enable selective and gentle operations.
The second case involves an image evaluation software modified by NASA researchers. The program originally served to eliminate interference from pictures of the sun or of cosmic nebulae and search them for details. Now, the researchers have adjusted the program so that it corrects blurred video images from security cameras. Among other things, this could help make visible the details of explosive devices used in bomb explosions.
