4DMedical is a global medical technology company focused on changing outcomes for people with lung disease by bringing more insights to medical imaging. We build software that helps clinicians move beyond “what it looks like” to clearer, quantitative information that can be used alongside the full clinical picture.

With offices in Melbourne, Australia and Los Angeles, California, we work with health systems, researchers, and clinical teams around the world to advance respiratory and cardiopulmonary imaging.

CT:VQ

CT:VQ™ is designed to generate quantitative, functional insights from contrast-free, routine CT imaging—helping clinicians better understand regional lung characteristics. The goal is simple: turn CT data into objective outputs that can support assessment and follow-up when interpreted in context with other clinical information.

Lung Health Imaging Panel

The Lung Health Imaging Panel is designed to expand the value of a thoracic CT by producing additional quantitative outputs that may be relevant to broader cardiopulmonary health. Components include:

• LDAi (Lung Density Analysis–Inspiration) – quantitative measures that may be relevant to emphysema assessment
• CAC (Coronary Artery Calcification) – quantification of a widely used imaging marker associated with cardiovascular risk
• IQ-UIP – quantitative analysis intended to support clinician review of imaging features that may be present in patterns consistent with UIP
• Lung cancer screening – tools to support standardized, consistent quantitative assessment in lung cancer screening CT programs

Built with clinicians. Success through collaboration.

We continue to partner with leading institutions to validate performance, improve usability, and integrate quantitative imaging into real-world workflows—so clinicians can access consistent measurements and track change over time.
