Lung Nodule Phantom

Phantom-Based Quality Assurance for Low-Dose CT Lung Cancer Screening

Support rigorous quality assurance while minimizing patient radiation exposure.

Key Advantages

Realistic Nodule Simulation for LDCT

The phantom incorporates lung nodules of different sizes and densities throughout both lung lobes, supporting realistic assessment of nodule detectability under low-dose CT conditions.

Anatomically Relevant Design

A semi-anthropomorphic design with tissue-equivalent materials and a bone-equivalent spine creates realistic imaging conditions for clinically relevant quality assurance.

Standardized QC for Lung Cancer Screening

Designed for low-dose CT lung cancer screening, the phantom supports reproducible quality control across different CT systems, reconstruction methods, and protocols.

Application Benefits

Realistic Anatomical Design

A semi-anthropomorphic design with lung-equivalent granules, a soft tissue-equivalent body, and a bone-equivalent spine creates realistic imaging conditions for quality assurance.

Ease of Use

Designed for routine quality assurance, the phantom can be easily positioned on the CT couch without additional stands or holders. Its compact design supports efficient integration into daily QA workflows.

Versatile Applications

Multiple lung-equivalent nodules of different sizes support realistic image quality assessment. Need to simulate larger patients? Simply add the Extension Rings.

Multiple Spherical Nodules of Different Sizes and Densities

Multiple spherical nodules of different sizes and densities support realistic image quality assessment under low-dose CT conditions. The phantom enables evaluation of nodule detectability in clinically relevant scenarios, including subtle findings such as ground-glass opacities (GGOs).

(Semi-)Anthropomorphic Phantom Design

A semi-anthropomorphic design with tissue-equivalent materials and a bone-equivalent spine with cortical and spongious bone components helps replicate realistic imaging conditions. Its compact and lightweight construction enables easy positioning on the CT couch and efficient integration into routine quality control workflows.

Extension Rings

Optional extension rings are available in different sizes and materials to simulate a wide range of patient anatomies. A dedicated configuration with pre-drilled holes also supports radiation dose measurements for quality assurance applications.

What Medical Physics Experts Say

“In LDCT, image quality represents a critical balance between minimizing radiation exposure and maintaining diagnostic confidence.

The phantom enables this balance to be assessed objectively and reproducibly by evaluating

whether lung nodules of varying size, density and contrast remain detectable when dose-reduced protocols are applied.”
