What term is used for phantoms that mimic the shape and size of a skeletal region?

• A. Anthropomorphic phantoms
• B. Simulated phantoms
• C. Anatomical phantoms
• D. Dynamic phantoms

Answer: (A)

The correct term for phantoms that mimic the shape and size of a skeletal region is anthropomorphic phantoms. These phantoms are specifically designed to resemble human anatomy in both structure and dimensions, which allows for more accurate simulations when conducting tests and calibrations, particularly in imaging modalities like bone densitometry.

Anthropomorphic phantoms play a crucial role in quality assurance and assessment of imaging systems, as they provide a realistic model for evaluating the performance of the equipment in a way that directly relates to patient anatomy. This enhances the reliability of diagnostic procedures and ensures the accuracy of bone density measurements in clinical practice.

Other types of phantoms, such as simulated phantoms, anatomical phantoms, and dynamic phantoms, may serve specific purposes but do not necessarily focus on closely replicating the anatomical features of skeletal regions as anthropomorphic phantoms do.
