Abstract

The invention relates to a medical image segmentation system and a medical image segmentation method based on deformation surface models, and belongs to the technical field of image processing. The medical image segmentation system comprises a model storing module, an input module, a display module, a locating control module and a segmenting module, so that the displaying module can be utilized to display medical images to be segmented based on user operation, and then displays double-layer deformation surface models corresponding to organs in the medical images acquired from the model storing module; the locating control module is utilized to locate the organ images in the medical images to be segmented between outer surface models and inner surface modules of the double-layer deformation surface models; and finally the segmenting module is utilized to segment and acquire the organ images of the medical images corresponding to the double-layer deformation surface models according to the double-layer deformation surface models. Therefore, segmentation of the medical images based on the three-dimensional deformation surface models can be realized, accuracy and automation of the segmentation of the medical images are greatly improved, and difficulty on segmentation is effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of image processing systems and methods, in particular to the technical field of medical image segmentation processing systems and methods, in particular to a medical image segmentation system and method based on deformable surface models. Background technique [0002] Medical images include images obtained by CT, positron emission tomography (PET), single photon emission tomography (SPECT), MRI (magnetic resonance imaging), Ultrasound (ultrasound) and other medical imaging equipment. With the successful application of imaging medicine in clinical medicine, image segmentation is playing an increasingly important role in imaging medicine. Image segmentation is an indispensable means of extracting quantitative information of special tissues in images, and it is also a preprocessing step and prerequisite for visualization. Segmented images are being widely used in various occasions, such as quantitativ...
