Joint Reconstruction for Phase-Cycled Balanced SSFP
Berkin Bilgic, Thomas Witzel, Himanshu Bhat, Lawrence L. Wald, Kawin Setsompop Martinos Center for Biomedical Imaging, Massachusetts General Hospital, Charlestown, MA, USA; Harvard Medical School, Boston, MA, USA; Siemens Medical Solutions, Charlestown, MA, USA. INTRODUCTION: Balanced steady state free precession (bSSFP) is an SNR-efficient technique that has found widespread use in cardiac, ab...
متن کاملJoint Reconstruction of Phase-Cycled Balanced SSFP with Constrained Parallel Imaging
Balanced SSFP is an SNR-e cient sequence with unique T /T contrast, but su ers from banding artifacts due to B sensitivity. These artifacts can be mitigated through RF phasecycling at a cost of signi cant increase in scan time. Here, we propose Joint L1-SPIRiT to jointly reconstruct highly accelerated/undersampled phase-cycled images and convert the di erent banding artifacts of these images in...
متن کاملSpectral Profile Design for Multiple Repetition Time Balanced SSFP
Introduction: Balanced SSFP (bSSFP) enables rapid image acquisition with high SNR but elicits an undesirable bright fat signal. Several steady-state sequence designs permit varying degrees of spectral shaping, allowing the fat signal to be suppressed by designing a stopband centered around the lipid resonant frequency [1-3]. Previous work on multiple repetition time (multi-TR) bSSFP has often r...
متن کاملRobust Multicoil Reconstruction for Phase-Sensitive Fat-Water Separation
Introduction: Phase-sensitive (PS) SSFP [1,2] is an efficient fat/water separation method, successfully used in several applications including angiography [1], musculoskeletal [3] and abdominal [4] imaging. It generates and detects a 180 phase-difference between fat and water. In previous work, water images reconstructed from individual coils with PSSSFP were combined [4,5]. However, abrupt spa...
متن کاملconstruction and validation of translation metacognitive strategy questionnaire and its application to translation quality
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
