基于DTI图像的脑干肿瘤术前路径自动规划设计
Design of Automatic preoperative path planning of brain Stem Tumor Surgery based on DTI
摘要
Abstract
Objective We proposed an automatic preoperative path planning method based on diffusion tensor imaging (DTI) for brain stem tumor surgery to effectively circumvent the important organizations and reduce the disability rate. Methods In this paper, DTI and magnetic resonance imaging (MRI) were combined effectively for the automatic preoperative path planning of brain stem tumor surgery. Firstly, DTI was corrected and registered with MRI. Then, the key region information of these two modal images was extracted for automatically designing the surgical path with gravity repulsion model and spline interpolation. Results Our method could complete automatic preoperative path planning through extracting the information of preoperative fiber bundle and tissue structure. In additional, it could realize the path planning intuitively and maximize avoid important tissue damage. Conclusion The proposed automatic preoperative path planning method based on the preoperative DTI can provide intuitive information for the doctors to avoid important tissue damage.关键词
