... x - rays dates to the early 1900s . This concept was based on the fact that if one plane or section of the body is kept fixed while the x - ray source and the film are moved , an unblurred image of the section of interest will result ...

... x - ray range . To effectively form the projection , we want all of the impinging x - ray lines to be parallel when they reach the object . This corresponds to an x - ray source infinitely far away , or , in practice , effective ...
