Overview
Precision-engineered rod phantoms for quantitative bone mineral density (BMD) calibration in CT and micro-CT systems. Manufactured using calcium hydroxyapatite (CaHA) embedded in a stable matrix, supplied as paired rods at defined mineral concentrations to ensure reproducible reference points for BMD analysis.

General details

• Each set includes paired rods at 0.3 g/cm³ and 1.25 g/cm³ CaHA for calibration across a clinically and preclinically relevant density range.
• Multiple diameters available to accommodate specimen sizes from small-animal models to human-scale samples.
• Compatible with clinical CT, micro-CT and other X-ray imaging systems for quantitative BMD calibration and validation.

Specification
Small Diameter Set (2 mm – 4 mm)
Designed for high-resolution imaging of small specimens:

• 2 mm rods: for very small bones such as mouse models
• 4 mm rods: for small-animal studies including rat bones
• Enables precise calibration in micro-CT systems with fine voxel sizes

Medium Diameter Set (8 mm – 16 mm)
Versatile option for mid-sized specimens:

• Suitable for rabbit, sheep and human tissue samples
• Balances resolution and signal for standard CT and micro-CT applications
• Ideal for translational research and preclinical studies

Large Diameter Set (32 mm)
Optimised for larger anatomical structures:

• Designed for human and large-animal bones, including vertebrae
• Provides robust signal and uniformity in clinical CT environments
• Ensures accurate BMD calibration at larger field-of-view settings

Key Features

• Dual-density rods: 0.3 and 1.25 g/cm³ CaHA
• Multiple diameters for species- and specimen-specific applications
• Designed for stability and reproducibility
• Compatible with CT, micro-CT and other X-ray imaging systems
• Provided as paired rods per set for direct comparative calibration

Applications

• Bone mineral density calibration
• Longitudinal preclinical bone studies
• Clinical CT quality assurance (QA)
• Cross-system and multi-site standardization

CT Images
Representative CT and micro-CT slices and renderings illustrating rod placement, contrast and imaging performance for the different diameters and densities are available to support protocol optimization.
