Segmented 3D Cartesian MR data acquisition using a randomized sampling pattern for compressed sensing image reconstruction |
摘要 |
A method of MRI for reduction of motion artifacts in 3D MR data acquisition with multiple segments comprises: the complete acquisition being divided into two parts: basic acquisition and complementary acquisition. Basic acquisition is performed at the beginning. Complementary acquisition is performed after the basic acquisition is finished. View Reordering is prepared for basic acquisition and complementary acquisition separately. Motion monitoring is performed regularly during the data acquisition. Whenever motion is detected, data acquisition stops. Image reconstruction is performed when motion occurs in the phase of complementary acquisition. The final reconstructed image is free of motion artifacts. |
