Field limiting device synchronized with scan motion

摘要

According to one embodiment, the x-ray apparatus includes an x-ray source adapted to emit an x-ray beam and a detector adapted to receive the x-ray beam of the x-ray source. The x-ray source is adapted to be moved in relation to a first portion of the x-ray apparatus and the detector is adapted to be moved in relation to a first portion of the x-ray apparatus. A control unit controls the movement of the x-ray source and detector. The x-ray source and the detector are adapted to rotate in relation to a first portion of the x-ray apparatus. Further, the x-ray beam is directed essentially towards the detector during the movement of the x-ray source and the detector.

主权项

1. An x-ray apparatus comprising:
a scan arm; an x-ray source configured to emit an x-ray beam and arranged on a first position of the scan arm; a detector arranged on a second position of the scan arm and configured to receive the x-ray beam; a field limiting device arranged on a third position of the scan arm, the field limiting device being configured to adjust a width of the x-ray beam as the scan arm moves; and a drive configured to move the scan arm through a series of movements including:
a) moving the x-ray source and the detector together in a first direction to a turning and then moving the x-ray source and the detector together in a second direction opposite to the first direction,b) concurrently moving the x-ray source and the detector in opposite directions.
