title: [Study of motion artifacts correction algorithm in optical coherence tomography images].
abstract: OBJECTIVE
  Optical coherence tomography images may be distorted by motion artifacts in dynamic imaging, so it may lead to misdiagnosis in clinical diagnosis. Motion artifacts correction has become an urgent issue in optical coherence tomography imaging.
  
  
  METHODS
  Firstly, using the improved complex nonlinear diffusion preprocessing filtering reduced the noise of the sequence images, then using the image mass center aligned the distortion data in the Y direction, finally, using the method of deviation average corrected motion artifacts along the Y direction.
  
  
  RESULTS
  After correction, the motion artifacts in the longitudinal 2D images and the 3D image disappeared, the surface of the 2D and the 3D image became more smooth, the structure between layers of the images got clear and distinct, retinal en-face single slice image was sharp, and the fundus tissue structure could be observed.
  
  
  CONCLUSIONS
  The algorithm of correction makes the physical structure of the retinal display truly after motion artifacts correction.
