We developed and evaluated a variable density Poisson disc undersampling technique and compressed sensing image reconstruction algorithm for free-breathing 3D cine steady-state free precession whole-heart imaging. In 10 patients, we found good agreement between 3D cine and conventional breath-hold 2D cine imaging measurements of ventricular volumes.
