  • Method and apparatus for imaging through 3-dimensional tracking of protons
    Patent number: 6281509
    Abstract: A method and apparatus for creating density images of an object through the 3-dimensional tracking of protons that have passed through the object are provided. More specifically, the 3-dimensional tracking of the protons is accomplished by gathering and analyzing images of the ionization tracks of the protons in a closely packed stack of scintillating fibers.
