A code was developed for generating X-ray images of bodies of any shape and spatial orientation. The bodies may be concave and have cavities. The geometrie of the bodies is defined by wire models which are displayed on the screen (in central projection) and can be modified by standard operations. The code allows for the following influencing effects: -- wavelength and wavelength distribution of X-rays -- quantity of absorbed photons -- wavelength dependent absorption coefficient of the material -- characteristics of the 2-dimensional detector array (e.g. dynamic range, -- quantum resolution, and noise) By taking into account the kinematics of the body (translation and rotation) image sequences showing realistic features can be generated. Therefore, the code is a most useful tool for testing of pattern recognition and tracking algorithms, particulary when using 3-D-kinematic predictor procedures. The method is applicable e.g. in ballistics or to non-destructive material testing of fast moving machine parts. The application of this code is not restricted to radiography. It may also be used in topics like absorption of infrared radiation in aerosols, light density variationes in fluid flows and similar phenomena.
