ABSTRACT:
This invention discloses an X-ray photography device having an X-ray tube associated with a primary diaphragm for defining or limiting the X-ray beam by partially blocking the same. The X-ray tube is mounted or carried in such a fashion that the beam can be directed at random towards any desired target. The device further includes a film cassette constituting a desired target which is similarly freely movable at random independently of the X-ray tube. Means are provided to accurately align the X-ray beam and target and to insure proper target coverage by the beam.
