ABSTRACT:
An x-ray bone densitometry system having an apparatus for positioning body parts is provided. The system includes a patient table having a length extending along a Y-axis and a width extending along an X-axis, a C-arm supporting an x-ray source at one side and an x-ray detector at an opposite side of the table, wherein the source and detector are aligned along a source-detector axis which is transverse to the Y-axis. The source is selectively energized and emits a fan beam of x-rays which conforms to a beam plane which is transverse to the Y-axis and contains the source-detector axis. A forearm positioner is removably supported on the table and includes an arm rest portion positioned at a selected distance along the X-axis from an edge of the table. A hand supporting member is configured to fit within the arm rest portion to maintain the position of a patient's hand in a predetermined shape when the source is energized.
