The DXA bone densitometer can be used to measure the bone density of the whole body or a single part.
HMQ-BDP bone density phantom, HMQ-BDP DXA phantom simulates the measurement environment of the human limbs and provides the ex vivo bone mineral content value of the limbs, so it is referred to as the limb bone density phantom.

HMQ-BDP bone density phantom,The limb bone density phantom (referred to as the limb phantom) is composed of radiation-equivalent solid water material [composed of polyethylene (C₂H₄) and a small amount of magnesium oxide (MgO) and calcium carbonate (CaCO₃)] and bone mineral [hydroxyapatite ( CasOH(PO₄)₃)] bone tube. The thickness of the phantom and the cylindrical bone sample simulated the test site and cylindrical bone.


Composed of a radiation-equivalent solid water material and a bone mineral cylinder, as shown in Figure A.1.

The length, width and height of the HMQ-BDP bone density phantom are 150x46x40mm, with 4 circular concave holes and 4 cylinders. The height of each cylinder is 28mm, and the diameters are (from large to small) 16mm, 13mm, 10m, 8mm.
