X-Ray Visualization and Analysis of Multicomponent Subjects

The information carried by x-rays showing the distribution of each material of which a subject is assumed to be composed is distributed on separate films by means of a controlled variation in composition of the scanning radiation. The beam is modulated, for example, by simultaneous motion of several...

Zusammenfassung:	The information carried by x-rays showing the distribution of each material of which a subject is assumed to be composed is distributed on separate films by means of a controlled variation in composition of the scanning radiation. The beam is modulated, for example, by simultaneous motion of several wedges. The method is useful in quantitative x-ray analysis and as a system for making radiographs predominantly sensitive to one material in the subject.
