摘要：
An X-ray apparatus is disclosed comprising an angularly adjustable parallelogram formed by two members parallel to a central axis and two members transverse the central axis. A radiation source and a radiation receptor are positioned at one end of the respective parallel members. The apparatus is characterized in that the two transverse members are disposed on opposite sides of the central axis, and one end of both parallel members is offset to the same side of the central axis.
