What is a common feature of phantoms used in bone densitometry?

• A. They are made from glass materials
• B. They simulate human bone properties
• C. They come in various colors for differentiation
• D. They require a special storage environment

Answer: (B)

Phantoms used in bone densitometry are specifically designed to simulate human bone properties, which is crucial for standardizing measurements and calibrating bone densitometry equipment. These phantoms are composed of materials that mimic the density and attenuation characteristics of human bone, allowing for accurate and reliable assessments of bone mineral density in clinical practice. By providing a controlled reference point, they enable the comparison of patient results against known standards, which is essential for diagnosing conditions like osteoporosis and for monitoring treatment efficacy.

While other features might be present in certain contexts, such as color differentiation for identification or environmental storage considerations, the primary and most critical aspect of these phantoms is their ability to accurately represent human bone characteristics. This focus on simulating the biomechanical and compositional properties of bone ensures that the densitometry results are reliable and meaningful for patient care.
