MRI-based navigation system for intracranial surgery

Abstract

The invention relates to an intracranial operation navigation system based on magnetic resonance imaging. The system includes a preoperative planning module, a positioning conversion module, a three-dimensional neuroimaging visualization module, a three-dimensional neuroimaging rapid segmentation module, and an intraoperative guidance module. The operation navigation system of the invention can apply a computer aided technology and a magnetic resonance imaging technology to an intracranial surgery process, effectively helps doctors to perform preoperative surgical planning and intraoperative surgical positioning and guidance, and assists surgical operation, thereby reducing difficulty of surgery and treatment accuracy and effects are improved.

Description

technical field [0001] The invention relates to an operation navigation system, in particular to an intracranial operation navigation system based on magnetic resonance imaging. The system is suitable for preoperative planning, intraoperative positioning and treatment of intracranial neurosurgery. Background technique [0002] The brain mainly includes the left and right cerebral hemispheres. It is the largest and most complex structure in the central nervous system. It is also the highest part and the organ that regulates body functions. It is the material basis of advanced neural activities such as consciousness, spirit, language, learning, memory and intelligence. For some special brain diseases, such as Parkinson's disease, epilepsy, etc., it is necessary to perform intracranial surgery. Because the intracranial structure is too complex, the high risk of intracranial surgery is high. For example, the patient's brain injury will be caused by the wrong operation of the do...

AI Technical Summary

Problems solved by technology

This method cannot observe in real time the relative position of the interventional surgical instrument and the patient's internal organs, nerves and other biological tissues, the quality of the image surgery, and even cause additional trauma damage to the patient.

[0005] 2. The results of magnetic resonance imaging are often about the overall image of the patient's brain and other important organs, but cannot provide real-time image information near the current surgical instrument arrival position

Therefore, it is impossible to guide the doctor to operate the surgical instrument to complete the more delicate operation during the operation.

[0006] 3. Doctors generally hold surgical instruments. For intracranial surgery, any hand shaking or other small operating errors may cause irreparable brain damage to the patient.
