Distribution of Breath Sound Images in Patients with Pneumothoraces Compared to Healthy Subjects : Diagnostic Yield of Vibration Response Imaging Technology

Vibration response imaging (VRI) is a new technology that provides a radiation-free dynamic lung image from the vibrations produced by airflow. The vibration energy from the respiratory cycle can be quantified for any lung region. This is obtained by integrating the energy profiles from 42 acoustic...
