CAE Blue Phantom
Ultrasound-guided procedure training that scores technique in real time, built for medical schools and teaching hospitals.
What was in the way
CAE Blue Phantom's simulation hardware was well established, but the software around it could not keep pace. Instructors had no way to assess a trainee's technique objectively, results were recorded on paper, and each teaching site ran a different local build. Rolling out a curriculum update meant visiting the hardware.
How we worked
Three decisions that shaped the engagement.
We separated the real-time simulation core from everything around it. The C++ engine kept its hard latency budget; assessment, curriculum and reporting moved to a cloud service that could be updated independently of the device.
Technique scoring was the hardest problem. Working with the clinical education team, we translated qualitative marking rubrics into measurable signals — probe angle stability, needle trajectory deviation, time to target — and validated them against instructor scores until the model agreed with expert assessment within an acceptable margin.
A web instructor console gave faculty cohort dashboards, curriculum assignment and remote build deployment for the first time, replacing site visits with a release channel.
What changed
Measured against the baseline recorded during discovery.
Teaching sites now run one version of the curriculum, updated centrally. Instructors assess against consistent criteria, and trainee progression is measured across cohorts rather than anecdotally.
“Objective scoring changed the conversation with faculty. We stopped debating whether a trainee had improved and started measuring it.”
