Abstract

The embodiment of the invention discloses a symmetry axis / symmetry plane extraction method and system based on craniocerebral image data, and solves the problems of subjectivity, large errors, low efficiency and the like in the prior art through the symmetry axis / symmetry plane extraction method based on craniocerebral image data. The method comprises the steps of obtaining a to-be-processed firstimage; turning over the first image along a turning-over shaft / turning-over surface to obtain a second image; registering the first image and the second image to obtain a registered transformation matrix; acquiring a symmetry axis / symmetry plane direction of the first image based on the rotation component of the transformation matrix; and obtaining the symmetry axis / symmetry plane of the first image based on the mass center of the first image and the symmetry axis / symmetry plane direction of the first image. According to the symmetry axis / symmetry plane extraction method and system, diagnosisdifferences caused by human factors can be eliminated or reduced, diagnosis errors are reduced, and the diagnosis speed is increased.

Description

technical field [0001] This description relates to the fields of medical imaging and computer technology, and in particular to a method and system for extracting symmetry axes / symmetry planes based on brain imaging data. Background technique [0002] With the development of computer technology, the clinical application of medical imaging has become more and more extensive. Medical imaging provides a great scientific and intuitive basis for the diagnosis of diseases, and can better cooperate with clinical symptoms, laboratory tests, etc., and play an irreplaceable role in the final accurate diagnosis of the disease; at the same time, it can be applied in treatment. For craniocerebral diseases, due to the symmetry of the cranium, it can be used as the basis for judging the lesion of the cranium. When a lesion occurs on one side of the cranium, the extent of the lesion can be judged by comparing with the opposite side according to the image data of the cranium. Therefore, it i...
