About 4DMedical
4DMedical is a global medical technology company that specializes in advanced software-based respiratory and cardiopulmonary imaging solutions. Their core offering, XV Technology®, utilizes patented algorithms derived from advanced aerodynamics research to process and enhance X-ray and Computed Tomography (CT) images. This technology allows for the dynamic quantification of regional lung ventilation and airflow throughout the entire respiratory cycle, providing clinicians with detailed, color-coded lung images and quantitative data in a report. This approach aims to detect subtle functional losses in the lungs earlier than traditional methods, potentially leading to more timely and effective treatment interventions.
For physicians, 4DMedical’s technology, delivered via a Software-as-a-Service (SaaS) model, integrates with existing imaging equipment, making it a non-invasive and accessible diagnostic tool. Key products include XV LVAS (X-ray Velocimetry Lung Ventilation Analysis Software) and CT LVAS (Computed Tomography Lung Ventilation Analysis Software), which provide insights into lung motion and airflow. Additionally, their CT:VQ™ product offers ventilation and perfusion insights from non-contrast CT imaging, comparable to SPECT V/Q studies but without the need for radioactive tracers. The company also offers a Lung Health Imaging Panel with components like LDAi (Lung Density Analysis–Inspiration) for emphysema assessment, CAC (Coronary Artery Calcification) for cardiovascular risk, and IQ-UIP for interstitial lung disease. 4DMedical’s solutions are designed to provide quantitative, actionable information to support diagnosis, disease monitoring, treatment planning, and surgical planning for a wide range of respiratory conditions, including those in veterans exposed to burn pits.

What Physicians Need to Know
4DMedical's technologies provide physicians with unprecedented, objective, and data-driven insights into regional lung function and airflow, enabling earlier and more sensitive detection of respiratory deficiencies. This can lead to more precise and personalized treatment plans for conditions like COPD, asthma, cystic fibrosis, and pulmonary embolism, even revealing subtle forms of small airways disease missed by conventional tests. The non-invasive nature and compatibility with existing imaging equipment streamline workflows and reduce the need for contrast agents or radioisotopes, improving patient safety and accessibility. The detailed, color-coded reports and 4D video visualizations offer clear, actionable information for diagnosis, care planning, and monitoring disease progression.
4DMedical's solutions, including XV LVASu00ae, CT LVASu2122, and CT:VQu2122, are delivered as Software-as-a-Service (SaaS) and are designed to integrate seamlessly into existing clinical workflows. They process images from conventional X-ray and CT equipment, eliminating the need for new hardware. The results, including quantitative reports and visual maps, are routed directly to PACS for review, minimizing workflow disruption. 4DMedical also integrates anatomical nodule detection and AI risk scoring into their CT platform, allowing for automated risk stratification within a single PACS interface.
What the Web Says
4DMedical is a global medical technology company specializing in respiratory imaging and ventilation analysis through its XV Technology platform. The company's technology converts standard CT scans into dynamic lung function imaging, aiming to revolutionize the diagnosis and management of lung diseases. While the technology is considered innovative and has secured deployments with leading US academic medical centers, the company is still pre-profit and its high valuation is a point of discussion among investors.
Overall: MixedStrengths
- Breakthrough and incredible technology for lung imaging and ventilation analysis.
- Non-invasive and avoids contrasting chemicals or nuclear medicine.
- High gross margins (87%) on its paper-scan cloud-delivered model.
- Strong revenue growth, compounding at 128% per year since FY2021.
- Clinical adoption gaining traction at prestigious institutions like Mayo Clinic, Stanford, and Cleveland Clinic.
- Positive employee sentiment regarding work-life balance, pay, benefits, job security, management, and culture (from 4D Global Medical Billing Company reviews).
Limitations
- High valuation despite being pre-profit and having relatively small absolute revenue.
- Concerns about short-selling activity and stock overvaluation.
- Product sales representatives may lack in-depth knowledge of the technology.
- Potential for siloed data and issues with third-party support providers for their 4D EMR software (a different product/company, but sharing a similar name).
- Management needs improvement (from 4D Global Medical Billing Company reviews).
- Time and location flexibility, inclusive work environment, and trust in colleagues are areas for improvement (from 4D Global Medical Billing Company reviews).
