TEE / TOE learning guide · 5 minutes · No account · Free Web access

Learn TEE anatomy in 3D and cross-section

Find a landmark in the four-chamber view, change the plane, then compare the two-chamber view. Three short exercises in the free Web simulator.

Find the same landmark in both views

Open the four-chamber preset. Find LA, LV, RA and RV in the model section, then locate the corresponding regions on the 3D heart. Point to the section to see that location in 3D.

Write one structure you identified in both panels.

Open four-chamber

22 minutes

Change one control, then explain the change

Choose Knobs or Horizontal sliders. Change the multiplane angle a little while watching both panels. Predict which structure the plane will meet before you move again. Re-select the preset to reset the pose.

What changed in the section? What stayed in the same place in 3D?

Practice with the controls

32 minutes

Compare two preset planes

Open the two-chamber preset and compare its plane with the four-chamber preset. Describe the plane orientation using the 3D model. Each preset opens a fresh model pose; it does not retain your manual adjustments.

Explain the difference to a colleague without naming the view.

Use it in your next teaching session

Share this guide before a tutorial or print the worksheet for a small group. Ask learners to predict, move one control and explain what changed. No learner account is needed. The worksheet includes links back to the free simulator.

Anatomy practice, alongside real echo teaching

Sections, heartbeat and valve motion are illustrative model views. They do not reproduce ultrasound acoustics or calibrated probe handling. Use real TEE/TOE images, textbooks and supervised teaching for clinical interpretation and scanning.
