Abstract
A portable x-ray bone densitometry system is suitable for transportation between rooms of a medical facility through generally standard doorways. The system has a base portion capable of rolling ambulation by at least one human operator during transportation and selective stabilization on a floor for patient scanning. The apparatus has 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 includes a central portion coupled with the base portion, and at least one table leaf coupled with the table central portion, for extending table length parallel to the Y-axis. The apparatus also has 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 to irradiate at any one time a scan line which is transverse to the Y-axis; and an x-ray detector, coupled with the source-detector support arm in alignment with the source at opposite sides of the patient table along a source-detector axis which is transverse to the Y-axis, for receiving x-rays from the source after passage thereof through the patient position. A scanning…
