    A new multi-scale Perlin noise method enhances virtual clinical trials for breast imaging by creating more realistic breast phantoms. This simulation technique improves anatomical noise modeling, closely matching patient data for better VCT accuracy.

    Area of Science:

    • Medical Imaging
    • Computational Anatomy
    • Biophysics

    Background:

    • Virtual clinical trials (VCTs) require realistic anatomical models for medical imaging simulations.
    • Accurate breast phantom development is crucial for advancing breast imaging VCTs.

    Purpose of the Study:

    • To propose and evaluate a multi-scale Perlin noise method for simulating breast tissue anatomy.
    • To improve the realism of breast phantoms for digital mammography and tomosynthesis simulations.

    Main Methods:

    • Utilized four Perlin noise distributions to model breast tissue compartments and Cooper's ligaments.
    • Simulated digital mammography and tomosynthesis projections using a clinical DBT system.
    • Performed power-spectrum analyses and Laplacian fractional entropy (LFE) calculations on phantom and patient images.

    Main Results:

    • Simulated images using the proposed Perlin method showed power-law spectra similar to clinical mammograms.
    • The proposed method demonstrated improved agreement in LFE estimates between phantoms and patients compared to prior methods.
    • Power-law exponents for patient, prior phantom, and proposed phantom images were -3.10, -3.55, and -3.46, respectively.

    Conclusions:

    • The proposed multi-scale Perlin noise method significantly enhances the simulation of anatomical noise in breast phantoms.
    • This improved simulation shows close agreement with breast parenchyma measures, advancing VCT capabilities.
