ABSTRACT:
An improved system and method for using dual energy techniques for acquiring x-ray images in two and three dimensions is disclosed. An X-ray source and detector are mounted at opposite ends of a movable C-arm. A fast movement mechanism is provided to quickly and precisely move the C-arm and detector in stepped motion about a patient. Low and high energy X-ray images are taken at each discrete step point, followed by fast movement of the source and detector to a next position with respect to the patient. Motion artifacts are eliminated by taking the high and low energy X-ray images while the C-arm is stopped. High and low energy pulses are provided through the use of a filtration arrangement which is synchronized with the frame rate of the detector to thereby optimize image collection.
