Step-by-step instructions
- For liver imaging, place the Passive Driver over the patient’s gown on the right side of the abdomen at the level of the xyphoid process.

- Secure the elastic belt snugly around the patient and Passive Driver to hold it in position and to minimize air gaps between the driver and the patient. This provides optimum transfer of vibrations into the liver. Make sure the belt is secure but not so tight that it restricts normal breathing. The patient’s arms can be positioned either above the head or at the sides.
