Abstract
Imaging different bone sites for medical education requires the formation of bone-equivalent materials that mimic bone density. We investigated an economic imaging composition that characterizes bone density in imaging for quality assurance and educational purposes. Four different compositions were tested to reveal the best composition in simulating bone density in X-ray imaging. Hydrated lime was discovered to be the most suitable because it is durable (stiff and does not crumble), easy to source and process, and attenuates imaging X-rays enough to resemble real bone. Hydrated lime provides a significantly better phantom than the other combinations used.

Summary
Radiologic anatomical phantoms are commercially available for quality assurance and educational purposes. These phantoms are considered expensive and do not demonstrate all pathological complications. Materials that can convincingly simulate bone in X-ray imaging, for educational and quality-assurance purposes, have generated great interest. Bone is composed of organic and inorganic compounds in the form of minerals. Living bone consists of 10% - 20% water and 60% - 70% minerals, with most of the rest comprising collagen and small amounts of other substances, such as proteins and inorganic salts [1]. Mostly collagen, represent 33% of total bone composition.
