[Introduction of a new method of study in legal medicine: high grade direct roentgen magnification with a 1 micron roentgen focus tube].

The 1 mu focal spot x-ray tube, which had been developed for industrial purposes, allows for the first time high grade direct radiographic magnification. The first results with this new technique in forensic medicine are presented. Due to the high proportion of soft radiation, tiny glass fragments which can not be detected with conventional radiographic techniques, are visualized in the radiographic magnification. Furthermore, these foreign bodies can clearly be differentiated from other contrasted structures, like dust particles, subcutaneous fat etc.
