This study proposed a parallel line Structure Light based Optical Motion Tracking system (SLOMO) and verified its feasibility in respiratory detection and motion correction in MR liver imaging.

Fig. 1 The setup of SLOMO system for abdominal imaging. SLOMO system consist of frame holder (a.) and optical module (b). Optical module is a camera-laser system for depth imaging

Fig. 4 Reconstruction results of motion corrupted and corrected images. Liver images were reconstructed into 4 phases according to the respiratory curves detected by bellow and SLOMO system.
