X-Ray Apparatus for Bone Density Assessment and Monitoring

An X-ray apparatus for measuring a patient's bone density, comprising:

• a housing for enclosing an internal frame;
• a motor for applying a motive force in a first direction;
• a gantry moving member in physical communication with said motor;
• a gantry having a base, a first end, and a second end, wherein said base is in physical communication with said gantry moving member;
• a radiation source configured to direct radiation through said first end, wherein said radiation source comprises a mono-energetic generator producing radiation at a first energy;
• a dual energy detector array located in said second end, comprising at least one detector element pair which comprises at least one high energy detector element and at least one low energy detector element;
• and
• an armrest area for positioning a patient's forearm in the apparatus wherein said armrest area is positioned between said first end and said second end.
