A novel phantom was developed to train radiologists in fluoroscopically guided transthoracic needle biopsy. This realistic training tool enhances radiologist confidence and proficiency before patient procedures.

Area of Science:

  • Medical Education
  • Radiology
  • Interventional Pulmonology

Background:

  • Transthoracic needle biopsy (TTNB) is a crucial diagnostic procedure for pulmonary lesions.
  • Training for TTNB requires realistic simulation to ensure proficiency and patient safety.

Purpose of the Study:

  • To design and evaluate a novel phantom for training fluoroscopically guided transthoracic needle biopsy.
  • To improve radiologist confidence and skill in performing pulmonary biopsies.

Main Methods:

  • Construction of a multi-material phantom simulating thoracic anatomy (skeleton, lungs, diaphragm, heart).
  • Inclusion of modeling clay to represent pulmonary lesions for biopsy simulation.
  • Utilized foam rubber, wood, aluminum, and rubber for realistic tactile and visual feedback.

Main Results:

  • A functional phantom was successfully created for TTNB training.
  • The phantom effectively simulates the anatomical structures and lesion characteristics encountered during biopsy.
  • The authors anticipate improved trainee performance and reduced anxiety in initial patient procedures.

Conclusions:

  • The developed phantom serves as a valuable educational tool for fluoroscopically guided transthoracic needle biopsy.
  • Simulation training with this phantom can enhance radiologist proficiency and confidence.
  • This approach offers a safe and effective method for practicing pulmonary biopsy techniques.
