Automatics Path Plan Algorithm for Hypertensive Cerebral Hemorrhage Surgery

With the aging of society, patients with hypertension are getting younger, and the number of patients with cerebral hemorrhage who need emergency surgery is increasing, the use of navigation and robot to do stereotactic minimally invasive surgery has gradually matured. However, the surgical path planning cannot be completed automatically, and the doctor's operating software is still needed to make subjective judgment and participate in the design and planning. In this paper, an automaticthree-dimensional spatial path planning algorithm is proposed for the surgery of brain hematoma. The path automatic planning algorithm includes: First, 3D brain model is generated based on patient brain medical image data; In the three-dimensional coordinate system, the three-dimensional model of hematoma was segmentate, and approximate shape of the segmentation by ellipsoid based the point cloud was used.
