About this project
A free, non-commercial teaching resource of the highest quality, built for medical residents and ultrasound techs/sonographers.
How a module works
Every exam is a complete learning module, not a reference article. Each one teaches you to acquire the view (with troubleshooting), recognize normal versus pathology, and then practice with interactive interpretation drills, measurement tasks graded against reference values, and a short quiz.
Accuracy & sourcing
Clinical content is anchored to authoritative society guidelines (ACEP, AIUM, ACR, ASE) and peer-reviewed references. Every image carries its source and license, and patient imagery is de-identified. The full data sourcing, licensing, and accuracy plan lives in docs/SOURCING_PLAN.md in the repository.
