Nine test images. Each row shows PLAX, PSAX, and A4C views. The first row asks for naming the numbered structures. The second row asks for extremities, the arrows point on. I.e. center top image: upper right arrow: right shoulder. Lower left arrow left hip. Center middle image: upper right arrow: left shoulder. Lower left arrow: right hip. Center bottom image: upper arrow (apex) left hip. Lower arrow (base): right shoulder. Right row: Top image: The arrow is pointing into the PLAX plane, therefore it points towards the right hip. Middle image: the arrow is pointing out of the PSAX plane, therefore pointing towards the left hip. Bottom image: The arrow is pointing into the A4C plane, therefore pointing to the anterior chest wall
