摘要： The present invention relates to a method and apparatus for reducing metal artifact in image reconstruction. In at least one embodiment, the method for reducing metal artifacts in image reconstruction comprises collecting at least one uncalibrated image (an X-ray or fluoroscopic image for example) and calibrating the at least one uncalibrated image, forming at least one calibrated fluoroscopic image. A patient to transmitter transform is computed using at least the at least one calibrated image. A reconstructed volume is formed using at least a patient to transmitter transform. At least two of the at least one calibrated fluoroscopic image, the patient to transmitter transform and the reconstructed volume may be combined, forming at least one display image. This image may then be displayed, using a display device for example.

摘要： Certain embodiments relate to a system and method for forming a virtual isocenter in an imaging system. The method includes determining a distance between a detector and an object to be imaged, determining a distance between a detector and source, varying either or both distances between image exposures, and adjusting image data obtained from the image exposures for a change in magnification between image exposures. The distance may be determined using a tracking system. The method may also include reconstructing at least one image of the object from the image data adjusted for the change in magnification. Additionally, a position of the object may be maintained at a virtual isocenter formed by varying the distance between the detector and the object and/or the source and the object. The method may further include moving a support including the detector and a source in a non-circular path to move the detector and the source around the object while varying the distance between the detector and the object.

摘要： This invention relates to a system to alert drivers and bicyclists of a pedestrian crossing in a crosswalk in nighttime or dark conditions. It uses road markings consisting of a fluorescent pigment installed on a pedestrian crossing. A sensor detects the presence of a pedestrian intending to cross at the crosswalk and then an ultraviolet light source, not visible to the pedestrian, is activated to irradiate the fluorescent road markings, which then emit visible light seen by the oncoming vehicle. The system communicates with a paired and identical alert system on the other side of the crosswalk to illuminate the road markings on both sides of the road and account for pedestrian crossing from either side.
