Idea
A vision-language model platform for 3D cardiac CT analysis enabling accurate cardiovascular diagnosis and risk prediction for clinicians.
Research Paper
Core Innovation
This paper introduces Cardiac-CLIP, a foundation model that uniquely integrates 3D cardiac CT images with standardized radiology reports using a two-stage pre-training approach. It combines self-supervised and contrastive learning to align visual and textual modalities, enabling superior cardiovascular abnormality classification and clinical prediction. This approach surpasses prior models by effectively leveraging large-scale multi-modal clinical data for improved diagnostic and prognostic performance.
