摘要
目的：利用计算机图像融合技术,探讨对颞骨岩部、颈内动脉、骨迷路等结构进行多模态医学图像的配准、融合与重建,为经岩骨入路手术术前计划的设计与模拟提供形态学基础.方法：收集患者头颅CT、MRA导航序列图像,利用复旦数字医疗自行研发的神经外科手术导航系统软件,进行影像数据的配准和融合,分别基于CT图像重建出颅骨和骨迷路,基于MRA图像重建出颈内动脉.结果：重建后的图像可单独或多结构融合显示颞骨岩部、颈内动脉和骨迷路的形态;三类结构用不同的伪彩色、透明度进行区别显示,能快速、直观地反映相互之间的位置和毗邻关系;能够根据手术入路,在三维空间中任意角度旋转观察.结论：利用头颅CT和MRA导航序列图像,经配准、融合和重建,显示颞骨内颈内动脉、骨迷路等复杂结构,为颅底外科解剖训练和手术计划提供一种新的方法和有效的信息补充.
Objective： Through computer image fusion technology, to explore multimodality image registration, fusion and 3-D reconstruction about petrous pyramid, internal carotid artery （ICA） and bony labyrinth and to provide preoperative design and simulation of the transpetrosal approach with morphologic basis. Methods： The navigation serial data of computed tomography （CT） and magnetic resonance angiography （MRA） were input to the workstation of excelim-04 surgery navigation system that was studied by digital medical research center of Fudan University, and corresponding work was executed including registration and fusion, and then the skull base and the bony labyrinth were reconstructed based on CT image of petrous pyramid, internal carotid artery was reconstructed built on MRA image. Results： The reconstructed image of petrous pyramid, ICA and bony labyrinth could be clearly displayed with one or multi-structures. Their position and relationship were distinguished by different pseudo-color and transparency. They could also be rotated, observed in any direction based on skull base surgery. Conclusion： Registration, fusion and 3-D reconstruction of clinical CT and MRA of head could clearly display skull base, bony labyrinth and internal carotid artery. It could provide a kind of new and valid method for anatomical training and surgical planning of skull base surgery.
