STEP 3: Editable clinical report to share with physician
What We Change
for Cardiologists
Clear functional FFR assessment directly from routine CT
Reliable identification of lesions that truly require intervention
Objective support for difficult treatment decisions
Seamless integration into existing workflow
What We Change
for the Patient
Less unnecessary invasive procedures. More personalized, evidence-based care
Reduced exposure to procedural risks
Earlier and more accurate detection of clinically significant disease
Better follow-up of intermediate stenoses over time
About Us
BIOME Science, founded in 2021, is developing CORONARY FLOW, the next generation AI diagnostic software transforming cardiac imaging using AI and physics, for the non-invasive assessment of coronary flow and stenoses.
BIOME improves clinical decision-making for the coronary heart disease treatment.
Our Mission
BIOME Science is building the next generation of AI diagnostic software for coronary artery diseases in CCTA imaging, which enables cardiologists to determine whether a lesion truly causes ischemia. As a result, patients are not sent for unnecessary invasive procedures, while it is ensured that the severity of a lesion is sufficiently monitored.
Our mission is to modify current engineering models & systems that fail precisely where real-world variability matters most: coronary intermediate lesions.

What we are working on
Addressing multifactor complexity of CAD
The Human & Systemic Problem
- Like cancer, CAD is a multifactor disease that current non-invasive tech fails to assess accurately
- Diagnostic uncertainty in intermediate lesions drives: → up to 60% of avoidable and sometimes dangerous invasive procedures → unnecessary stenting → procedural complications with increased healthcare costs → Poor and inefficient CAD screening and monitoring
- False positives lead to overtreatment. False negatives delay critical intervention. Physicians lack a reliable, fast, non-invasive tool for accurate patient CAD detection, decision and monitoring.
CORONARY FLOW AT A GLANCE
We are building the next generation of AI diagnostic software bringing precision medicine in cardiac imaging to resolve the grey zone in coronary heart disease and provide:
- High negative & positive predictive FFR values
- Visualizes plaque burden + vessel wall
- Accurate first-line test in stable chest pain
- Seamless integration in clinical workflows
Why experts trust us
BIOME developed a CCTA-driven FFR engine that merges data learning with physics through a unique AI architecture.
This advanced non-invasive engine will resolve the intermediate lesions clinical “grey zone” in CAD, where diagnostic decisions are currently uncertain.
By combining in-house physics-based computational tools, experimental hemodynamic validation, and multi-factor clinical data, this hybrid model achieves very high accuracy compared to invasive wire-based FFR, offering physics-grade reliability at AI speed.
Physics-driven architecture does not simply look for correlations in imaging data, but models the patient-specific physiological factors in a unified framework.

Glossary
Coronary flow glossary
FFR
FFR* (Fractional flow reserve) is a pressure- based index of the functional significance of epicardial coronary stenoses. It is defined as the ratio of the hyperemic distal pressure to the aortic pressure.
Angioplasty
Angioplasty* is a procedure used to open blocked coronary arteries caused by coronary artery disease. It restores blood flow to the heart muscle without open-heart surgery.
BMI
BMI* (Body Mass Index) - is a numerical value of your weight in relation to your height.
Stenosis grey zone
The FFR grey zone* refers to intermediate coronary lesions being arterial narrowing of moderate severity—typically 40–69% stenosis with FFR values ranging approximately from 0.7 to 0.85.
CCTA
The CT Coronary Angiography (CCTA)* is a medical imaging modality that uses X-rays to visualize the coronary arteries in search of narrowing and/or calcifications.
ICA
Invasive Coronary Angiography (ICA)* has long been regarded as the gold standard for diagnosing and assessing coronary artery disease in patients with stable angina.
Comorbidities
Comorbidities* refer to medical conditions that exist alongside a primary diagnosis and can impact your overall health, treatment, and prognosis.
CMD
Coronary Microvascular Dysfunction (CMD)* is defined as impaired blood flow to the microcirculation.
CAD
Coronary artery disease (CAD)* is a prevalent heart condition characterized by the buildup of atherosclerotic plaque within the arterial lumen.
