1. Product Introduction and Structure
The mold body is a cylindrical shape with a diameter of 80 mm and a height of 60 mm. I, II, III, and IV represent small cylindrical bodies with diameters of 20 mm and lengths of 40 mm, each having different densities. Among them, the centers of I and III are on the same straight line, and the centers of II and IV are also on the same straight line, and these two lines are perpendicular to each other.The centers of I, II, III, and IV cylindrical bodies are on a circle with a diameter of 40 mm. The basic material of the mold body is soft tissue and similar materials (polyurethane resin), with a purity of over 99%. The materials in regions I, II, III, and IV are hydroxyapatite (HA), and the corresponding bone densities are 50 mg/cm³, 100 mg/cm³, 200 mg/cm³, and 300 mg/cm³, as shown in Figure A.1.

Key Features
Standardized Multi-Insert Design:
- Features 4 equidistant Φ20mm inserts and one central Φ40mm insert, each calibrated to simulate different bone and soft tissue densities.
- Arranged in a circular pattern for consistent positioning and uniform imaging across scans.
High-Precision Density Calibration:
- Manufactured with precisely controlled, traceable density values to match typical human bone density ranges (e.g., cortical and trabecular bone equivalents).
- Designed to meet international standards for bone densitometry equipment calibration.
Stable, Durable Construction:
- Encased in a homogeneous, radiopaque base material (typically epoxy or polymer) with long-term dimensional and density stability, suitable for repeated use in clinical labs.
Multi-Purpose Calibration:
- Ideal for routine quality control, equipment performance verification, and cross-scanner comparison of BMD measurement accuracy.
- Supports calibration of both DXA and QCT systems, making it versatile for different bone densitometry modalities.
Applications
- Bone mineral density (BMD) scanner calibration
- Dual-energy X-ray absorptiometry (DXA) system validation
- Quantitative computed tomography (QCT) bone density testing
- Clinical lab quality control and regulatory compliance
- Research and cross-scanner comparison studies
