Method and apparatus for measuring x- or {65 -radiation absorption or transmission at plural angles and analyzing the data

摘要: In apparatus for examining a body by means of X or Y radiation, two-dimensional matrix elements the is exposed to radiation from number directions and transmission plurality paths small cross-sectional area through measured, numbers being such that each element intersected group which intersect different groups elements. From these measurements, absorptions transmissions in individual are calculated used produce cathode ray tube display and/or photograph.
