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.
