AbstractAbstract
[en] A new radiographic method (Nuclear Scattering Radiography) is described. Its physical foundation, potentialities, results of investigating the structure of some biological objects, including human tissues, are given. The method is based on the use of proton-proton elastic scattering and proton quasi-elastic scattering on nuclei at 600-1000 MeV energies. This method widely takes advantage of potentialities of a modern physical experiment. To derive an information concerning the character of interaction and the coordinates of particle passage the drift or proportional chambers, as well as scintillation counters are utilized. The computer realizes the control for apparatus operation and data collection. The position of an interaction point is reconstructed by using the particle passage coordinates. The event number depends on the density of matter. The hydrogen events and interactions with nuclei could be separated, thus it is possible to get both ''hydrogen'' and ''ordinary'' radiograms. The method permits to obtain a new independent diagnostical information on the object structure. The optimization of experiment and increasing arrangement operation speed permits to lower considerably a radiation dose and exposition time
