Method and system for cone beam x-ray source and detector arrangement in computed tomography systems |
摘要 |
Methods and systems for x-ray detector and x-ray source arrangement in cone beam computed tomography systems are provided. An arm having a first end and a second end is mounted onto a support structure such that the arm rotates about a vertical axis. An x-ray source and an x-ray detector are separately attached to each end of the arm at angles in a range of about 2 to 20 degrees from the vertical axis, such that each is adapted to rotate with the arm about the vertical axis. The x-ray source and the x-ray detector are spaced apart to enable an anatomical target to be interposed between the x-ray source and the x-ray detector for cone beam computed tomography scanning, such that the x-ray source and the x-ray detector do not interfere with the target during scanning.
