Computer-assisted planning for neurosurgery: a clinical study

To investigate the clinical effect of computer-assisted planning for neurosurgery (CAPN). 100 groups of directional targets were randomly sampled. The targets' directional three-dimension coordinates measured with CAPN and those measured by traditional reading device were analyzed statistically. CAPN was actualized in 137 cases of stereotactic operation. The data measured with CAPN and those with traditional reading device were analyzed with two samples. The paired t test showed no statistically significantly difference between the data of targets measured by both methods (t < t(0.05/2,99)=1.984, P >< 0.05). Different kinds of operation based on CAPN were performed upon 137 cases success fully. CAPN was proved reliable. All operations were successful and the clinic effects satisfactory. CAPN is accurate and reliable, and has positive effect on the improvement of stereotactic neurosurgery.
