X-ray bone densitometry apparatus

摘要

An X-ray bone densitometry system comprising a base portion and a patient table extending parallel to a Y-axis of an XYZ coordinate system for supporting a patient at a patient position. The patient table has a central portion coupled with the base portion, at least one table leaf coupled with the table central portion for extending table length parallel to the Y-axis, a source-detector support coupled with the base portion, an X-ray source, coupled with the source-detector support, for emitting a beam of X-rays, an X-ray detector, coupled with the source detector support in alignment with said source at opposite sides of the patient table, for receiving X-rays from the source after passage thereof through the patient position, and a scanning mechanism moving at least one of the patient table and the source-detector support relative to the other to scan the patient position with said X-ray beam. The system may be adapted to be portable by providing the base with rolling ambulation means.
