CS_MoCo_LAB

Compressed Sensing and Motion Correction LAB: An MR acquisition and reconstruction system

Generate a Compressed Sensing (CS) accelerated MR sequence and reconstruct the acquired data online on the scanner by means of Gadgetron or offline on an external workstation.

Acquistion

• Generic subsampling class for Compressed Sensing acquisitions
• CS accelerated gradient echo sequence (2D, 2D+time, 3D, 3D+time): CS_FLASH (Siemens, VB20P)
• MR motion imaging sequence (4D, 5D): CS_Retro (Siemens, VB20P, VE11C, VE11P)

Reconstruction

• CS and motion-resolved reconstruction system for Gadgetron (C++)
• CS reconstruction system in Matlab (including a GUI)
