What is it indicated for?
CT: V software is a non-invasive image processing technology that measures volume changes from paired inspiration-expiration CTs to quantify and visualize regional and global ventilation. These regional measures are derived entirely from the lung tissue displacement and lung volume change between the paired inspiration-expiration chest CTs.
CT: V is for use in adult patients. Quantification and visualizations are provided in the form of a report.
CT: V may be used when physicians need a better understanding of a patient's lung function and/or respiratory condition.
Indications for use as stated in the FDA summary.
