Area of Science:

Medical Simulation
Augmented Reality in Medicine
Radiology Training

Background:

Current CT-guided intervention training relies on mentored approaches with real patients.
Simulation is a recognized valuable tool in medical education.
This project explored replicating CT-guided interventions using augmented reality head-mounted displays (ARHMDs).

Purpose of the Study:

To assess the feasibility of simulating CT-guided interventions with AR.
To evaluate user acceptance and effectiveness of the AR simulation as a training tool.

Main Methods:

A virtual patient model was created from CT data.
The ARHMD projected a virtual patient mesh, with needle and phantom tracking via RGB cameras.
Virtual CT slices were generated on voice command, and the system was trialled by radiologists.

Main Results:

16 users trialled the AR simulation, providing feedback.
11 users found the realism adequate for training purposes.
12 users reported increased confidence in CT biopsy skills post-simulation.

Conclusions:

Augmented reality simulation of CT-guided procedures is feasible.
The developed simulator shows potential as an effective tool for clinical practical skills training.
The system allows for adjustable case complexity to match trainee needs.
