LAPNet: Non-Rigid Registration Derived in k-Space for Magnetic Resonance Imaging
IEEE Transactions on Medical Imaging(2021)
摘要
Physiological motion, such as cardiac and respiratory motion, during Magnetic Resonance (MR) image acquisition can cause image artifacts. Motion correction techniques have been proposed to compensate for these types of motion during thoracic scans, relying on accurate motion estimation from undersampled motion-resolved reconstruction. A particular interest and challenge lie in the derivation of re...
