Abstract: A method and an x-ray apparatus produces a standard set of x-rays of a person's head while he or she is in a prone position. A movable frame is rigidly connected to a table, such as an operating table, and an extendible arm having a receiver for an x-ray source at a distal end provides for placement of the x-ray source in various, fixed positions. Right and left lateral cephalograms, an anterior-to-posterior cephalogram, and right and left transcranial views of the temporomandibular joint are provided by the fixed-position x-ray source. A panorama x-ray machine is also movably engaged with the frame for taking panographic images. A first set of cephalograms can be taken of a patient on an operating table, and the portable x-ray apparatus can be moved away from the operating table. A surgical treatment objective can be overlaid on the first set of cephalograms.
