Training system for US-guided lung interventions

Key Investigators

Project Description

The aim of the project is to develop a training system that provides a quantitative report regarding the use of a low-cost lung phantom [1] in ultrasound-guided interventions, particularly for core needle biopsy (CNB).

A phantom with several embedded solid inclusions was fabricated. These inclusions are colour coded thus, a qualitative report can be used to indicate the success of a CNB procedure. However, a quantitative analysis is required. For this reason, the development of a training system is planned.


  1. Objective A. Fabrication of dedicated phantom
  2. Objective B. Setting up the system’s tools
  3. Objective C. Application development

Approach and Plan

  1. Phantom model –> Accurately replicated thoracic tissues (lung, ribs, and solid masses) providing a useful tool for training ultrasound-guided procedures
  2. Tools connections via Optitrack and Plus Toolkit (Telemed and Clarius US System, needle for biopsy)
  3. Application development

Progress and Next Steps

  1. Fabrication of dedicated phantom –> In progress to establish the virtual model
  2. Design of tracking fixtures for equipment –> In progress
  3. Optitrack + US System setup –> Connection to SLICER
