1. A fluoroscopy machine comprising:
- an x-ray source producing a beam of x-rays along an axis;
a support arm having a first end attached to the x-ray source and having a second end opposite the x-ray source along the axis so as to provide a space along the axis between the first and second ends sufficient to accommodate a human patient;
an x-ray detector attached to the second end of the arm and positioned to receive the x-rays along the axis and provide image electronic signals;
a tracking device providing object location and orientation signals an image processor receiving and processing the image electronic signals and the object location and orientation signals to provide adjusted image signals; and
a display device including;
(i) image optics producing an image from the adjusted image signals;
(ii) a head mount for attaching the image optics to a person'"'"'s head to move therewith and so that the image is displayed to a person wherein the display device is within the person'"'"'s field of view;
wherein the image is adjusted for at least one of rotation, translation and perspective distortion with respect to the display device.

Abstract
A fluoroscopy machine includes an x-ray source and detector mounted in spaced relation to a support arm, an image processor and a display device. The display device includes image optics attached to a head mount wearable by a person, such as a physician or technician. The image displayed by the image optics can be processed by the image processor to present an orientationally accurate image corresponding to the head mount wearer'"'"'s field of view. For example, the image can be processed to correct for angle of rotation, translation and/or perspective distortion.
