Digital x-ray images taken before a surgical procedure by a fluoroscopic C-arm imager are displayed by a computer and overlaid with graphical representations of instruments be used in the operating room. The graphical representations are updated in real-time to correspond to movement of the instruments in the operating room. A number of different techniques are described that aid the physician in planning and carrying out the surgical procedure.
1. An x-ray imaging device comprising:an x-ray source for generating cycles of x-ray radiation corresponding to an image acquisition cycle; an x-ray receiving section positioned so that x-rays emanating from the x-ray source enter the x-ray receiving section, the x-ray receiving section generating a
1. An x-ray imaging device comprising:an x-ray source for generating cycles of x-ray radiation corresponding to an image acquisition cycle; an x-ray receiving section positioned so that x-rays emanating from the x-ray source enter the x-ray receiving section, the x-ray receiving section generating an image representing intensities of the x-rays entering the x-ray receiving section; a computer coupled to the x-ray receiving section; radiation sensors located in a path of x-rays emitted from the x-ray source, the radiation sensors detecting a beginning and an end of a radiation cycle and transmitting the detected beginning and end of the radiation cycle to the computer; a dynamic reference frame marker attached in a fixed position relative to a patient; a calibration and tracking target; and a tracking sensor for detecting a position, in three-dimensional space, of the dynamic reference frame marker and the calibration and tracking target; wherein the computer determines that an image acquisition cycle is erroneous when the, position of the calibration and tracking target moves relative to the position of the dynamic reference frame during an image acquisition cycle.
