4DMedical provides FDA-cleared four-dimensional lung imaging technology, to deliver insights into airflow and quantify regional lung function during a patient’s tidal breath cycle.
Our Non-Contrast CT:VQ™ is the world’s first non‑contrast post‑processing technology that transforms routine, chest CTs into quantitative, lobar ventilation (V) and perfusion (Q) maps—without injected contrast or radioisotopes. Delivered via software-as-a-service, results are returned directly into the radiology workflow for interpretation alongside the source CT images.
Our XV Lung Ventilation Analysis Software (XV LVAS) is a first, as an imaging modality to provide functional lung imaging without the use of a contrast agent. A simple protocol using existing hospital fluoroscopy captures X-ray images and then using our proprietary flow velocity measurement technique, XV Technology provides a four-dimensional view of lungs.
