The goal of this project is to develop and test a system that uses controlled airway oscillations and real-time, non-contrast X-ray fluoroscopy to visualize regional lung ventilation.

Project Overview

The goal of this project is to develop and test a system that uses controlled airway oscillations and real-time, non-contrast X-ray fluoroscopy to visualize regional lung ventilation. The device will generate non-invasive periodic changes in airway pressure and lung air volume at known frequency and amplitude. These changes in X-ray intensity can be detected through spectral analysis using the X-ray pulsatility index (XPI) method. The project aims to determine whether externally induced airway oscillations can provide a practical method for mapping regional lung ventilation without contrast agents. Ultimately, to identify an airway oscillation frequency that produces a detectable ventilation-related signal and can be clearly distinguished from a simplified 1 Hz cardiac signal.
