| 摘 要： | 为了提高神经外科手术导航系统(IGNS)的精确度,我们提出了一个基于线弹性模型的脑组织变形矫正系统(BDCS)来预测脑变形误差。在本文的研究中,通过两例肿瘤切除手术病例对本系统的精确度进行验证。使用该系统后,开颅后脑组织的平均位移误差由(4.97±3.53)mm降至(1.00±0.63)mm,平均预测率为(72.27±20.37)%。实验表明,该系统操作方便,快速,预测精度较高,是一种非常有希望应用于临床来矫正脑组织变形的方法。 |

| Abstract: | In order to increase the accuracy of image guided neurosurgery (IGNS), we developed a brain deformation corrective system (BDCS) based on linear elastic model. To investigate the fidelity of such a system, two cases of cerebral tumor resection were conducted in our paper. According to our experiments, the average shift error after craniotomy was reduced to (1.00 +/- 0.63)mm from (4. 97 +/- 3. 53)mm and the average prediction rate was (72.27 +/- 20.37)%. The results showed that the system was convenient and fast to operate and presented a promising pathway to compensating for brain deformation during neurosurgery. |
