The cardiovascular life hidden inside every planning CT.

A multidisciplinary program transforming routinely acquired radiation treatment planning computed tomography into a comprehensive cardiovascular precision medicine platform — no extra scans, no extra radiation, no extra patient burden.

Scientific Mission

Build one of the world's largest cardiovascular imaging programs — from data that already exists.

Every planning CT already visualizes the heart, coronaries, great vessels, valves, chambers, epicardial fat, thoracic aorta, pulmonary arteries, skeletal muscle, adipose distribution, vertebral bone and pulmonary parenchyma. We extract, quantify, and connect this latent physiology to lifetime cardiovascular outcomes.

Opportunistic Screening

Turn every treatment planning CT into a cardiovascular assessment — coronary calcium, aortic and valvular calcification, chamber size, epicardial fat, and body composition.

Dose–Structure Atlas

Map delivered radiation dose to every cardiac substructure — LV, RV, atria, LAD, RCA, LCx, valves, pericardium, conduction system, aorta — and link to lifetime cardiovascular events.

AI Cardiovascular Phenotyping

Deep-learning segmentation and biomarker extraction across thousands of studies, producing scalable, reproducible imaging phenotypes.

Radiomics Discovery

Tens of thousands of texture, shape and heterogeneity features translated into predictive signatures for toxicity, recurrence and survival.

Toxicity Prediction

Models integrating imaging, dosimetry, EHR, labs and cancer therapy for heart failure, arrhythmia, MI, stroke, and cardiovascular mortality.

Precision Radiation Planning

Baseline cardiovascular phenotype informs beam selection, dose constraints, heart avoidance, proton selection and adaptive planning.

Partnership

Three institutions. One shared platform.

A durable operational, scientific, and clinical alliance built to sustain a multi-decade cardiovascular oncology imaging program.
