Fluoroscopic chest imaging with 4Dx technology software analysis

4DxV utilizes a novel software algorithm to analyze data from cinefluoroscopy images to calculate regional ventilation and pulmonary function changes. Cinefluorography uses a fluorescent screen with X-rays to make real-time moving images the lung described below. This is the same x-ray fluoroscopy that is used in clinical imaging and the fluoroscopic imaging time is approximately 1 minute leading to an effective radiation dose of 2 mSv (200 mRem). This is significantly lower that the radiation exposure from a standard chest CT. Fluoroscopy images are acquired at each of five views for approximately enough time to capture at least one complete, continuous breath. The subject is required to remain in the same position for each of the five fluoroscopy imaging sequences. These images will be analyzed by the novel 4Dx technology to provide the 4Dx lung function analysis report.
