This study introduces a novel vascular phantom using real human vessels for improved imaging evaluation. This realistic model enhances the accuracy of ultrasound and CT imaging for various vascular conditions.

Area of Science:

  • Biomedical Engineering
  • Medical Imaging
  • Vascular Research

Background:

  • Vascular phantoms are crucial for evaluating imaging modalities like ultrasound (US) and CT.
  • Existing phantoms often lack the precise geometry and pathological features of human vasculature.
  • Previous models, including latex tubes and agar molds, had limitations in anatomical accuracy.

Purpose of the Study:

  • To develop and evaluate a novel vascular phantom utilizing a real human vessel.
  • To assess the phantom's efficacy in mimicking human vasculature, including pathologies like plaques and calcifications.
  • To compare imaging results from the novel phantom using multiple modalities.

Main Methods:

  • A phantom was constructed using a formaldehyde-fixed human vessel section within an agar-filled acrylic box.

Related Experiment Videos

  • The vessel was cannulated onto acrylic tubes to simulate blood flow pathways.
  • Imaging evaluation was performed using X-ray angiography, CT, and 3D B-mode US.

    • Main Results:

    • The phantom demonstrated good correlation with anatomical features such as lumen, plaques, and calcifications across imaging modalities.
    • X-ray angiography, CT, and ultrasound images showed consistent representation of the vessel's geometry and pathology.
    • Minor discrepancies and artifacts were identified and discussed, providing insights for future improvements.

    Conclusions:

    • The real vessel phantom offers a more anatomically accurate and pathologically representative model compared to previous phantoms.
    • This advanced phantom is highly suitable for evaluating and validating medical imaging techniques, including projection radiography, CT, and US.
    • The potential exists to extend its application to magnetic resonance (MR) and US-based flow studies.
