A new anthropomorphic torso phantom aids ultrasonographer training by simulating upper abdominal organs and soft tissue masses. This realistic training tool uses advanced materials for accurate ultrasound imaging and skill development.

Area of Science:

  • Medical Imaging
  • Biomedical Engineering
  • Ultrasound Technology

Background:

  • Ultrasound training requires realistic anatomical models.
  • Current training phantoms may lack fidelity in simulating complex abdominal structures.
  • Developing advanced phantoms is crucial for improving diagnostic ultrasound skills.

Purpose of the Study:

  • To describe the design and construction of an anthropomorphic torso phantom for ultrasonographer training.
  • To create a training tool that accurately mimics upper abdominal anatomy and ultrasound characteristics.
  • To provide a platform for practicing the identification of simulated soft tissue masses.

Main Methods:

  • An anthropomorphic torso phantom was constructed, representing the upper abdomen.

  • Simulated organs include liver, kidney, gallbladder, aorta, and bowel gas, with ribs.
  • Ten soft tissue masses with varied echographic patterns were embedded in the liver.
  • Tissue-mimicking materials were used, matching speed of sound, attenuation, and density.

    • Main Results:

    • The phantom accurately represents upper abdominal anatomy.
    • Simulated masses exhibit diverse and typical echographic patterns.
    • Tissue-mimicking materials provide realistic ultrasonic properties.
    • Construction details and sample images are provided.

    Conclusions:

    • The described phantom is a valuable tool for foundational ultrasonographer training.
    • It offers a realistic simulation of abdominal ultrasound imaging scenarios.
    • The phantom facilitates the development of essential diagnostic skills using ultrasound.
