Summary
This study introduces a new, accessible framework for creating intravascular ultrasound (IVUS) phantoms. The method uses finite element analysis and Field II to simulate realistic IVUS imaging conditions, aiding research calibration.
Area of Science:
- Biomedical Engineering
- Medical Imaging
- Computational Modeling
Background:
- Intravascular ultrasound (IVUS) phantoms are crucial for calibrating and evaluating imaging processing tasks.
- Current phantom generation methods are often not the primary focus, lack comprehensive coverage, and rely on inaccessible, multi-platform solutions.
Purpose of the Study:
- To present a novel, unified framework for generating representative IVUS phantoms under varying intraluminal pressures.
- To provide an accessible and single-platform solution for researchers in the field.
Main Methods:
- Utilized the finite element method (FEM) for mechanical modeling and Field II for ultrasound simulation.
- Developed a workflow involving coronary cross-section modeling, region identification, mesh generation, intraluminal force application, deformation computation, and speckle noise incorporation.
Main Results:
- The framework successfully generated IVUS phantoms, validated against known studies and expected values for contrast, noise, and strain.
- The developed toolbox is freely accessible and fully implemented on a single platform.
Conclusions:
- The proposed framework offers a standardized, accessible, and effective method for creating IVUS phantoms.
- This advancement facilitates more robust calibration and evaluation of IVUS imaging processing techniques.
