Proposes a mechanics-grounded foundation model that generates individualized 4D cardiac motion conditioned on ECG electrophysiology, addressing temporal and spatial misalignment between ECG and physical motion.
Problem
ECG records electrical activity that drives cardiac motion via electromechanical coupling, but its temporal delay and low spatial resolution cause misalignment with physical motion, limiting ECG use beyond event/segment-level tasks.
Approach
Uses cardiac mechanics as a foundation to bridge ECG electrophysiology and 4D cardiac motion, generating individualized motion conditioned on ECG (details not stated in the abstract).
