Abstract

The embodiment of the invention discloses a target area image segmentation system and device. The system may comprise: a processor configured to: obtain an image of a target object and information ofa to-be-segmented target region included in the image; determining at least one target region segmentation model according to the information of the target region to be segmented, wherein each targetregion segmentation model in the at least one target region segmentation model is used for segmenting different sub-regions; and inputting the image into each target region segmentation model to obtain a segmented image of each sub-region, and determining the target region segmented image of the target object according to the segmented image of each sub-region. According to the technical scheme provided by the embodiment of the invention, each target region segmentation model can be flexibly combined according to the information of the target region to be segmented, so that the target region segmentation image can be obtained more quickly and accurately, and the problems of complicated process and long consumed time caused by manual target region sketching on the image by a doctor are effectively solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular to a system and device for image segmentation of a target region. Background technique [0002] Radiation therapy, chemical drug therapy, and surgical therapy are the main means of tumor treatment. In particular, the accuracy of the delineation of the target area, which is closely related to the above methods, will directly affect the therapeutic effect. Due to the large differences in the target volume of each patient, doctors need to manually outline the target volume on the target volume image, but the delineation process is too cumbersome and time-consuming. Contents of the invention [0003] Embodiments of the present invention provide a target region image segmentation system and device, which can automatically segment an image according to the specificity of the target region of the target object, and obtain the target region segmented im...
