Abstract
An imaging device for ionizing radiation, X-rays, gamma rays, or neutrons comprises in succession: a scintillator for transposing the ionizing radiation into electromagnetic radiation (.nu.) in the ultraviolet spectrum, a gas detector coupled to the scintillator and designed to respond to the received radiation by forming an avalanche A of electrons that ionize the gas thereby providing intense light that is optically detectable, An imaging system serves to record the image of the electron avalanches that ionize the gas in the gas detector The device is applicable to medical, biomedical, or industrial radiography imaging devices.
Claims13
An imaging device for X-rays, gamma rays, or neutrons, the device being characterized in that it comprises, in succession:
- a scintillator for transposing ionizing radiation into electromagnetic radiation in the ultraviolet spectrum;
- a gas detector coupled to said scintillator and receiving said ultraviolet spectrum electromagnetic radiation, said gas detector containing a gas and being designed to respond to the received ultraviolet radiation by forming an avalanche of electrons causing said gas to be ionized, with intense light emission taking place substantially from a point;
- and
- an imaging system responsive to said light emission and suitable for recording an image of electron avalanches that cause the gas in the gas detector to be ionized.
