Due to heart rate variability, Cardiac Magnetic
Resonance requires the determination of a cardiac phase
model to reconstruct trigged or cine images. Calibration
of such a model can be personalized on a patient basis
using a 1D+t phase contrast real time acquisition.
Benefit of an automatic calibration in term of temporal
precision of the predicted systole phase has been tested
on twenty-three healthy volunteers. Personalized
adaptive cardiac model predicted end-systolic time
better than global model on the whole population.
Personalization of subject-specific cardiac model is
feasible automatically in MRI and reduces the prediction
error of systole.
