1. An apparatus for performing diagnostic proton radiography of a human subject comprising:

  • a source of negative hydrogen ions;

    a synchrotron connected to the source to receive the negative hydrogen ions and accelerate them in an orbit to a precisely controlled predetermined value of energy;

    means connected to the synchrotron for stripping the accelerated negative hydrogen ions to produce a beam of protons and extract the beam from the synchrotron;

    means for disposing the human subject in the beam of protons;

    means for sweeping the beam of protons in a predetermined pattern to traverse a portion of the human subject;

    a proton detector disposed to receive the portion of the beam that traverses the human subject and to detect a parameter of the protons received thereat; and

    display means connected to the sweeping means and the detecting means to produce from information about beam position and beam intensity a proton radiograph of the subject.
