Synopsis

The report will focus on neurosurgery of the brain and introduce some advances in magnetic resonance-image guidedminimally invasive diagnosis and treatment. First, through multi-contrast magnetic resonance image, 3D map of criticalstructures and function of the brain could be extracted, and a complete surgical planning is carried out. The detection electrode or treatment device could be placed in the detection or treatment position accurately by the surgical robot, and the temperature of the ablation zone is monitored in real time in Laser-Induced Thermal Therapy to achieve preciseablation. The core technologies and solutions are discussed.
