Parallel magnetic resonance image technology of GRAPPA-SENSE

WANG Da,BAO Shang-lian(Beijing Key Laboratory of Medical Physics & Engineering,Institute of Heavy Ion Physics,Peking University,Beijing 100871,China)  
Parallel magnetic resonance image technology has been widely used in MRI field.A novel method named as GRAPPA-SENSE was proposed in this paper.GRAPPA-SENSE was developed using generalized autocalibrating partially parallel acquisitions(GRAPPA) algorithm to intervene more missing lines in central K-space in order to generate accurate coil sensitivities for self-calibrating sensitivity encoding(SC-SENSE) algorithm.This method was tested by using experimental data of a standard water phantom,and the results demonstrated that the image quality had been improved.
