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.

Objective

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 US-guided procedures
2. Tools connections via Optitrack and Plus Toolkit (Telemed/Clarius system and needle for biopsy)
3. Application development

Progress and Next Steps

1. Fabrication of dedicated phantom –> Virtual and recontructed model finished
2. Tracking fixtures for the required equipment –> Biopsy needle (Bard 22mm), Telemed MicrUs EXT-1H L12 Probe. Extra tools and some adjustments to be implemented
3. 3D Models of the equipments –> Biopsy needle (loaded and extended) and Telemed US system
4. Optitrack + US System setup –> Connection to SLICER via Plus Toolkit using Telemed US System. Issues to connect the Clarius US system to be solved
5. Preliminar tracking system working –> New calibrations to be performed after upgrading the fixtures
