The aim of this work lies in designing software used for preoperative planning of the surgical access risk. In order to obtain a realistic and useful simulation we focused our study on the physical modeling of the brain targeting and on the maneuvers of the surgical instruments. A new method of intact surface construction, which will assist in accurate neurosurgical planning, was discussed. Moreover, the three-dimensional model and its visualization were described. This visualization method allows of combining the calculated data about the surgical intervention risks with the geometrical data describing patient's head. Therefore, this methodology will help to build an intelligent system that has the ability of selection the best approach of surgical intervention access. The current technique is based on geometrical synthetic object creation, this object “in next stages of the surgical planning approach†would be applied directly to the data describing the risks of surgical access, and this in turn will allow estimating the real risk value of the surgical access. The advantage of this method is that the creation of the object is based on surgical access approach. The best surgical access is based on finding the smallest distance of surgical intervention toward the target, taking into the account the reduction of brain tissue damage. The method of the intact vertex can significantly reduce the amount of memory overloading, also a method of filtration used to extract artifacts resulting in unreal vertices, caused in rendering errors and memory overloading, was used. Also, using data describing the correlation between the object vertices allows arifacts filtration without any need for additional transformations. All that improves the rendering procedure and the accuracy of the surgical intervention by 30%.
