Lung densities


Quibim has developed an automated suite with a patented algorithm that analyzes CT volume datasets to quantify different imaging biomarkers: lung and vessel volumes, low densities volumes and their regional distribution, and 15th percentile of Hounsfield Units (HU) of the lungs. The tool enables to perform lung detection, mask extraction and fixed thresholding in CT volume datasets. The solution also provides quantitative data about the volumes of the lungs, vessels, emphysema and air trapping through their regional distribution. This data is quantified by thirds and enables to detect the affected regions at an early stage and to follow up patients with COPD, lung emphysema, fibrosis, air trapping and pulmonary hypertension.
