To develop a robust single breath-hold approach for volumetric lung imaging at 0.55T.Method
A balanced-SSFP (bSSFP) pulse sequence with 3D stack-of-spiral (SoS) out-in trajectory for volumetric lung imaging at 0.55T was implemented. With 2.7× undersampling, the pulse sequence enables imaging during a 17-s breath-hold. Image reconstruction is performed using 3D SPIRiT and 3D l1-Wavelet regularizations.
