Problems solved by technology

(2) The contrast between the facial nerve and the surrounding tissue structure is low
These methods directly introduce features from the encoder to the decoder, ignore the effectiveness of feature aggregation at different levels, limit the effective utilization of features and introduce misleading features, thus causing the facial nerve to be confused with other regions

Abstract

The present invention disclosed a facial nerve segmentation method and device that decoupled decoupled division. The characteristics of small and low contrast between the face -to -face nerve structure and low comparison, build a facial nerve segmentation model that contains characteristic extraction modules, coarse splitting modules, and fine splitting modules, and uses feature extractionBased on the module extraction of low -level features and high -level features at different levels, the global search and fusion of facial nerve characteristics is used to use thick -dividing modules to make facial nerve characteristics at different levels, and then use the fine segmentation moduleAfter the comprehensive center's main characteristics and low -level features obtain the characteristics of the edge details, the characteristics of the center of the center's subject and edge details are extracted to obtain the facial nerve segmentation diagram.Plan planning before implantation of cochlear implantation.

Description

technical field [0001] The invention relates to the field of medical image processing, in particular to a facial nerve segmentation method and device for decoupling and dividing. Background technique [0002] Robotic cochlear implantation, an automated treatment to restore hearing to patients, relies on precise preoperative planning to avoid damage to critical anatomical structures. The identification of pericochlear tissue structures plays a crucial role in preoperative path planning. Among them, damage to the facial nerve may lead to permanent temporofacial nerve palsy, which is the most important tissue structure around the cochlea, and the distance between it and surrounding tissues is less than 1 mm. However, accurate segmentation of the facial nerve faces two major challenges: (1) The facial nerve structure is very small. The facial nerve only occupies a very small area in the CT image (in a 512×512-pixel whole-brain CT image, the facial nerve area only has 9-16 pixe...
