Cardinal Movements

---

Sliding involves moving the entire probe in a specific direction to find a better imaging window. This motion is typically used to locate the optimal window, explore different areas of the body, or follow a structure like a vessel.

Tilting involves moving the probe side-to-side along its short axis (imagine fanning your face with your hand). This motion allows for visualization of multiple cross-sectional images of a structure.

Rocking involves moving the probe along the long axis,  towards or away from the probe indicator. This helps center the area of interest while keeping the image in-plane throughout the adjustment.

Rotation involves turning the probe along its central axis (clockwise or counterclockwise). This is often used to transition between the long and short axes of a structure, such as a vessel, the heart, or the kidney.
