The brain deforms during neurosurgery, resulting in a decrease in the accuracy of the image guided neurosurgery system (IGNS). In this study, a wireless transmission-based brain shift compensation system (WBSCS) is implemented. The system consists of a laser range scanner for acquiring a cortical surface, and a mobile workstation equipped with a brain deformation correction software platform. The brain tissue deformation correction software platform includes a three-dimensional visualisation module, a calibration module, a brain tissue extraction module, a meshing module, a boundary condition acquisition module, a finite element calculation module, a preoperative image update module, and a communication module. The system exchanges data with the IGNS through wireless communication. The authors used five pigs to test the system. Results of experiments show that the system can compensate for brain deformation. It worked with IGNS to provide brain-shift-compensation-based guidance, improving the accuracy of the IGNS.
