[Computer-assisted planning for neurosurgery: a clinical study].

OBJECTIVE: To investigate the clinical effect of computer-assisted planning for neurosurgery (CAPN). METHODS: 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. RESULTS: 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. CONCLUSION: CAPN is accurate and reliable, and has positive effect on the improvement of stereotactic neurosurgery.

Skin image segmentation based on energy transformation.

In this paper, a new method on extraction of human skin grid centerlines is proposed. The method introduces the physics concepts of kinetic and potential energy into image processing. Regional energy is calculated. Energy transformation is performed to map the pixels from the grayscale space into energy space. Then, the energy image undergoes a morphological filter to remove noises and spurious minima. The amount of filtering can be manually tuned to get a different result. Subsequently, normal curvature of the energy surface is utilized to identify the principal direction and principal curvatures. The ridge centerlines can be detected at the image locations where the principal direction is perpendicular to the normal vector. The experiment shows that this method is an effective one for the purpose of extracting human skin grid.
