Safer Methods to Decrease Exposure to Harmful X-rays in Mammographies or Breast Radiography
NASA scientists, in conjunction with industry and academic researchers, discovered a safer method to decrease exposure to harmful X-rays in mammographies or breast radiography. Usually, physicians make more than one exposure to arrive at an X-ray film of acceptable density. Now the same solar cells used to convert sunlight into electricity on space satellites can make a single exposure sufficient. When solar cell sensor is positioned directly beneath X-ray film, it can determine exactly when film has received sufficient radiation and has been exposed to optimum density and then cut off the radiation. Reduction of mammography to single exposures could not only reduce X-ray hazard significantly, but double the number of patient examinations handled by one machine.
