Variability of myocardial perfusion dark rim Gibbs artifacts due to sub-pixel shifts (2009)

Ferreira, Pedro, Gatehouse, Peter, Kellman, Peter, Bucciarelli-Ducci, Chiara, Firmin, David

Abstract Background Gibbs ringing has been shown as a possible source of dark rim artifacts in myocardial perfusion studies. This type of artifact is usually described as transient, lasting a few...

1082 Free-breathing single-shot DENSE myocardial strain imaging using deformable registration (2008)

Le, Yuan, Kellman, Peter, Bennett, Eric E., Lin, Alex, Chefd'Hotel, Christophe, Lorenz, Christine H., ...

Free-breathing scans are often desirable in patients who find breath-holding difficult. We present a new approach for free-breathing myocardial strain imaging with displacement-encoding (DENSE) [1]....

OPTIMIZATION OF A HIGH SENSITIVITY MRI RECEIVE COIL FOR PARALLEL HUMAN BRAIN IMAGING (2008)

Patrick J. Ledden, Peter Van Gelderen, Peter Kellman, Yuxi Pang, Renxin Chu, ...

Two eight-channel MRI receive-only coils were developed to provide whole-brain coverage at 1.5 T and 3.0 T field strength, respectively. Objectives were an image signal-to-noise ratio superior to...

Time Integrating Optical Signal Processing. (2002)

Bader,Todd R., Kellman,Peter, Shaver,Harry N.

Optical signal processing architectures using time integration on the detector array provide a highly flexible, multipurpose, wideband, realtime processor. A key feature of the time integrating...
