Although non-linear reconstruction has shown potential
for shortening acquisition times, its clinical usage is
often hampered by the lengthy reconstruction time. To
speedup non-linear reconstruction and enable its
clinical usage, we have extended previously published
Gadgetron framework to support cloud computing. With
this extension (named GT-Plus), any number of Gadgetron
processes can run cooperatively across multiple
computers. GT-Plus framework was deployed on Amazon EC2
cloud and NIHs Biowulf system. We demonstrate that with
the GT-Plus cloud, a multi-slice free-breathing
myocardial cine imaging with the whole ventricular
coverage can be completed within 1min, including data
acquisition and reconstruction.
